Acid-Spewer Dragon: Too expensive for a bad body and irrelevant ability.
Akoum Hellkite: Not enough Mountains in the deck to make use of the ability frequently and the minimal damage is insignificant.
Alabaster Dragon: Ability might as well be flavor text with how useless this is.
Amareth, the Lustrous: Hard to get enough value with top of deck manipulation for such an expensive dragon that can draw cards.
Ambitious Dragonborn: Non flying dragon common that gets walled pretty easily by anything.
Amethyst Dragon: Decent utility removal spell but not for EDH.
Ancestor Dragon: Not too terrible a dragon. Usually, can’t make enough creatures to justify the life gain ability but possible to help if you deck build correctly.
Ancient Hellkite: Too red mana dependent for insignificant ability.
Ancient Brass Dragon: Any of the lower rolls will most likely not net you any creatures on top of having to connect with an attack.
Ancient Bronze Dragon: Good for growing power but hard to take advantage of counters other than just making large power dragons.
Ancient Copper Dragon: Powerful ramp but felt unnecessary now space wise with everything else going, including current price tag.
Ancient Gold Dragon: Difficult to leverage the tokens immediately for damage and expecting them to live a full turn.
Ancient Silver Dragon: The card draw is nice but expensive as well as expecting to cast all the cards you draw efficiently.
Ao, the Dawn Sky: More low cmc or token based dragon to use either ability.
Arashin Sovereign: Recurable but very difficult to punch through in attacking which makes it hard to justify.
Arcades Sabboth: Always want to be swinging with dragons making the static ability worthless and upkeep cost is always hard with how mana hungry the deck is.
Arcades, the Strategist: Better as Commander of a defender deck than part of a dragon deck.
Archwing Dragon: Want to keep dragons on the board to keep swinging rather than bouncing it every turn which isn’t necessary.
Atsushi, the Blazing Sky: Too generic for card drawing and better ramping options to justify over competition.
Astral Dragon: Cool art but don’t have fodder permanents to make use of the ability that I feel comfortable throwing away.
Avaricious Dragon: Not good on curve and only good when you’re out of cards in which case you’re probably losing anyway.
Avenging Hunter: Not enough Dungeon support to be worth including.
Backdraft Hellkite: Not enough instants and sorceries in the deck to make use of.
Beledros Witherbloom: Life total payment is too step in this deck that isn't abusing it.
Belltoll Dragon: Too expensive for a bad body and irrelevant ability.
Bhaal's Invoker: If you're pouring the mana into this ability, you probably aren't winning the game in anyway.
Bladewing the Risen: Recursion isn’t that bad with him and the pump ability may come up but would much rather have mass recursion than single target.
Bogardan Hellkite: Too expensive of a dragon with a low impact ability at that mana cost.
Boltwing Marauder: Better in a deck that makes a lot of creatures to pump the ability with.
Bone Dragon: 10/10 art. 0/10 ability. Pretty much a vanilla dragon.
Boneyard Scourge: Ability very easy to trigger but the body is too small to matter.
Brainstealer Dragon: Better in a theft/exile focused deck.
Brimstone Dragon: Better dragons at this cost with better abilities than just haste.
Broodmate Dragon: Splitting threats into two bodies is nice but not necessary to me.
Canopy Dragon: Why can’t the card have both trample AND flying?
Catacomb Dragon: Dragons are usually to big for the reduction ability to matter.
Chaos Dragon: Fast and efficient beater but random attacks can end up not letting you do what you want when you need to kill someone specifically.
Chardalyn Dragon: Common expensive dragon not really worth anything.
Chromium: Big expensive flyer that is difficult to get through chump blockers
Chromium, the Mutable: Better in a control heavy meta and discard can help with more graveyard-oriented cards.
Clockwork Dragon: Too many hungry to keep counters on him
Cloud Dragon: Not blocking non-flying creatures is pretty bad.
Covetous Dragon: Needs artifacts for a vanilla dragon? No thanks.
Crimson Hellkite: Red mana restrictive for a single target ability.
Crosis, the Purger: Only hits one player and hard to name colors to get the payoff every time against non mono colored decks.
Crystal Dragon: Nice utility for some recursion but would rather be running mass recursion than single target.
Cunning Breezedancer: Not enough non creatures and pumping a creature without trample isn’t good enough.
Darigaaz Reincarnated: Very good at being a recurable beater without an investment but with so many already in the deck and for not recurring himself immediately, he wasn’t necessary now.
Darigaaz, the Igniter: Only hits one player and hard to name colors to get the payoff every time against non mono colored decks.
Deathbringer Regent: Great as a utility creature for field wiping as a dragon but usually we’re the aggressor causing the field wipe to happen so we would want it one sided.
Demanding Dragon: Only hurts one opponent and there’s usually a lot of free permanents for players to sac in
Commander for the ability to be effective.
Destructor Dragon: One time removal spell dragon for such a high cost isn’t worth it. Would much rather have a different removal spell.
Draco: Hilarious and can usually cost 7 mana but will most likely just be a vanilla 7/7.
Draconic Muralists: Would rather have actual and cheaper tutors that are more reliable.
Dragon Broodmother: Not aggressive enough and takes too long to see up tokens to make impactful swings even though the Ur-Dragon synergy is good.
Dragonborn Looter: Would rather be playing efficient card draw/looter effects than stapled to a creature.
Dragon Egg: Extremely small dragon. No room for babies.
Dragon Hatchling: Smaller dragon. See above.
Dragonlord Atarka: Cost is a bit too expensive now for the amount of damage for a one-time removal spell can be.
Dragonlord Kolaghan: Overcosted mass haste dragon with niche use against decks that can run multiple of the same creatures.
Dragonlord Ojutai: Power crept dragon that's difficult to make effective use of consistently in the 99 versus other options now.
Dragonlord Silumgar: The steal effect is nice but this dragon usually is never wanting to attack and if there’s a problematic walker/creature, taking the permanent isn’t going to help you that much to where you’re already losing or you could just kill them.
Dragon Mage: Refilling our hand is nice but filling 3 other player’s hand isn’t good for us.
Dragon Tyrant: Excellent beater but the upkeep cost is very real with 4 red mana.
Dragon Whelp: Medium sized dragon. Not good enough to make the cut.
Drakuseth, Maw of Flames: Cool payoff of being able to swing but very expensive to throw out without guarantee of swinging.
Dream Pillager: Colored mana restriction at any point and having enough in general to cast their cards is very difficult to achieve.
Dread Linnorm: Nice combat trick and provides some protection/surprise blocking but there are better effects for cheaper mana cost.
Dromar, the Banisher: Bounces your own creatures sometimes which isn’t good. Would rather have a dragon that kills opponents or mass wipes their creatures.
Earthquake Dragon: Very difficult to make use if you’re behind and can’t get the cost reduction which will probably come up a lot of the time.
Ebon Dragon: Single target discard is very bad in Commander.
Elder Land Wurm: Weird ability for a dragon but there’s better abilities at 6 mana.
Emerald Dragon: An unnecessary effect for this deck as there's too many things going on in a game to leverage a one time Stiffle.
Enduring Scalelord: Don’t put enough counters on dragons for the ability to matter.
Eternal Dragon Good recursive ability and ramping with plainscycling but requires a lot of mana to get going and you only have so many plains in the deck.
Exalted Dragon: Don’t want to be sacrificing lands and not progressing your game plan.
Fallaji Dragon Engine: Pretty weak prototype card for an ever more mediocre actual creature.
Fang Dragon: Better field wipes for Dragon decks.
Fire Dragon: Not enough mountains and times to keep reusing the ability to make use of.
Firestorm Hellkite: Great beater but Cumulative Upkeep starts getting expensive really quick.
Firkraag, Cunning Insitigator: Better suited as the leader of a Goad deck instead in a dragon deck.
Flameblast Dragon: Very mana intensive for single target removal.
Fledgling Dragon: Too small of a Dragon.
Foe-Razer Regent: Not enough fighting synergies with all dragons to justify the abilities.
Forgestoker Dragon: Most creatures that can block dragons usually kill so spending the mana to stop that isn’t worth it.
Freejam Regent: Not enough artifacts to reduce to cost and pump ability isn’t relevant.
Furnace Dragon: Better in a big artifact meta. Not enough artifacts to reduce the cost sufficiently.
Furnace Whelp: Too small of a dragon.
Furyborn Hellkite: Very easy to get Bloodthirst effect but also very difficult to get through consistently.
Galazeth Prismari: Better to lead a deck for more artifacts to tap for mana. Perfectly reasonable for budget build as its a cheap dragon that slightly ramps you.
Ganax, Astral Hunter: Good budget dragon for ramp but there are more powerful options.
Glorybringer: Very mana efficient for all aspects but getting use every other turn can be slow at times.
Harbinger of the Hunt: Very efficient in a token meta but not necessary with other options available.
Hellkite Charger: Would rather runways to guarantee a second combat or even more for cheaper mana cost.
Hellkite Hatchling: Not enough creatures to sac most of the times to make it big enough.
Hellkite Igniter: Not enough artifact synergy.
Hellkite Overlord: Another very expensive but good beater that just couldn’t make the cut.
Hellkite Whelp: Insignificant ability on an insignificant body.
Henge Guardian: I wouldn’t even count this as a dragon.
Herdchaser Dragon: Too expensive for a bad body and irrelevant ability.
Hoarding Broodlord: Better in an exile focused deck than Dragons.
Hoarding Dragon: Not big artifacts that are worth tutoring for the in deck.
Hoard-Smelter Dragon: Artifact removal is nice but would much rather cast a big dragon to kill the player
instead as there are very few artifacts that prevent us from attacking.
Hunted Dragon: Nice stats but depending on the group giving the knights to someone may never be a good strategy.
Hypersonic Dragon: Not enough instants/sorceries we care about having flash for.
Icefall Regent: Only makes itself harder to interact with rather than all the dragons we have.
Imperial Hellkite: One-time tutor on a stick is nice but would rather have a cheaper tutor than 8 mana.
Intet, the Dreamer: Without any top manipulation, there’s chances where you can completely miss casting spells
Jugan, the Rising Star: If this dragon dies, that usually means the rest of the board is getting destroyed too making the counter’s irrelevant.
Junji, the Midnight Sky: Discard can sometimes enable opponents and depending on your opponents to have creatures worth reanimating isn’t as often as you’d like.
Juvenile Mist Dragon: Only stopping 3 creatures isn’t enough for Commander.
Kairi, the Swirling Sky: Better in a spellslinging or mill deck that you can rebuy and reuse multiple times.
Keiga, the Tide Star: If this dragon dies, that usually means the rest of the board is getting destroyed too making the gain control have no targets.
Khorvath Brightflame: I’m ashamed this card has the creature type Dragon.
Kilnmouth Dragon: Very expensive pinger but sometimes difficult to have enough Dragon cards in hand to
consistently give it a bunch of counters.
Klauth, Unrivaled Ancient: Felt a little top heavy on top of the other staples and more of a build around dragon than inclusion.
Knollspine Dragon: Either draw too many cards or can’t draw any cards with how the deck sequences.
Kyodai, Soul of Kamigawa: More budget friendly and single target indestructible isn't impactful enough.
Kokusho, the Evening Star: Without recursion effects to constantly abuse the dying trigger, the life gain is irrelevant.
Korlessa, Scale Singer: Having only 25% percent of your deck be actual dragons make this card dead the other 75% of the time.
Korvold, Fae-Cursed King: Great value engine as a Commander but as a Dragon you usually don’t have a lot of
other permanents you want to be sacrificing.
Kura, the Boundless Sky: Better suited for a lands/token deck strategy than just getting more generic land drops to make.
Lava-Field Overlord: Assist doesn’t justify a one-time effect to hit a creature and mediocre body.
Lightning Dragon: Ain’t nobody got time to pay Echo cost.
Lightning Shrieker: Great keywords, awful ability.
Livaan, Cultist of Tiamat: Not running enough non creature spells to make use of a creature that also be easily chump blocked.
Loch Dragon: No cost reduction and a small body with a draw effect we have better cards for.
Lotus Guardian: 6 mana signet? No thanks.
Lozhan, Dragons' Legacy: Not being able to pick off Commanders is pretty big and there is harder to remove permanents that offer the same type of effect.
Lurking Green Dragon: Draft common that basically can’t attack until your opponent’s let you.
Malfegor: Discarding your hand is never good and sometimes the opponents don’t have any or too many creatures
to sacrifice.
Mana-Charged Dragon: Great for Politics but when you end up being the Raid Boss, nobody wants to pay mana, so the effect doesn’t happen.
Mindscour Dragon: Milling opponents isn’t the game plan with this deck.
Mirrorwing Dragon: Not enough instants to abuse the ability with and too much risk of getting blown out from
other instants opponents have.
Manaform Hellkite: Better in a spellslinger type of deck than creatures.
Mist Dragon: Weird art. Weird combination of abilities. Not needed.
Moltensteel Dragon: More of a combo dragon usually for paying the life to buff which isn’t what the deck is about.
Moonveil Dragon: Better and cheaper costed buffs for dragons out there than this.
Moonveil Regent: Card draw usually isn’t consistent enough and the damage ability isn’t impactful enough.
Mordant Dragon: Great ability but for only being on itself, usually isn’t relevant.
Murktide Regent: Better in an instant/sorcery deck.
Nalathni Dragon: Too much text on the card for me to consider.
Necromaster Dragon: The zombies and milling are unnecessary for the main strategy.
Nesting Dragon: Fetch lands make token creation easy but not being able to really abuse these extra tokens for extra value.
Nicol Bolas: Great payoff for hitting an opponent if you manage to get through. Hard mana requirement and
upkeep cost.
Nimbleclaw Adept: Better and cheaper effects than untap only two things.
Niv-Mizzet Reborn: Not enough dual color cards to consistently net cards all the time.
Niv-Mizzet, Dracogenius: Better ways to draw cards off dragons in the deck than his personal ability.
Niv-Mizzet, the Firemind: More combo-oriented Dragon than a normal one.
Niv-Mizzet, Parun: Excellent payoff but the mana cost as well as no cost reduction from Ur-Dragon makes it really hard to justify in the deck.
Noxious Dragon: Very few creatures we care about destroying less than 3 mana.
Numot, the Devastator: Only blowing up one person’s lands doesn’t help you win.
Oceanus Dragon: One time goad effect is pretty low impact.
Obsidian Charmaw: More budget friendly and not enough abuse of ETB to hit multiple lands that could be problematic.
Ojutai, Soul of Winter: If you’re swinging with enough dragons to tap a lot of permanents, you usually kill them in the air already.
Opportunistic Dragon: Humans can’t block dragons and gaining control of artifacts isn’t necessary if we can’t even use them.
Ore-Scale Dragon: A sometimes cheaper vanilla dragon isn’t worth it.
Oros, the Avenger: Better dragons that can wipe all creatures than specific ones.
Palladia-Mors: Great beater but restrictive and high mana cost along with upkeep cost.
Palladia-Mors, the Ruiner: Great beater but hexproof never really matters which is the reason to run this card.
Pardic Dragon: No point of putting this on suspend so what’s the upside here?
Patron of the Arts: Better and easier token producers in other dragons.
Pearl Dragon: White dragons don’t do a whole lot I’ve noticed.
Phantasmal Dragon: Any small abilities targeting and making us removal this dragon sounds not worth the risk.
Phyrexian Dragon Engine
: Only really works if you're constantly pairing it with Mishra, Claimed by Gix
.
Predator Dragon: Usually don’t have a lot of creature to devour.
Preyseizer Dragon: See above.
Pristine Skywise: Don’t have a lot of instant speed cards to untap and surprise people with this dragon as that’s the main purpose of running it.
Prossh, Skyraider of Kher: Great commander, not great in the 99.
Pseudodragon Familiar: Common bulk trash.
Quicksilver Dragon: Targeted removal usually is hitting other dragons so the ability doesn’t become used.
Ramos, Dragon Engine Building up counters to create mana takes too long or sometimes isn't possible with some draws of multiple mono color spells.
Rakdos Pit Dragon: Never want to be Hellbent and a dragon you must pay mana to make fly is bad.
Rapacious Dragon: Small body that’s inherently cheap with treasure you get back but not worth the space.
Rathi Dragon: Never want to be sacrificing lands.
Reckless Barbarian: There are a million better ramp spells than this creature.
Renari, Merchant of Marvels: Flash dragons are cool but only having one effect in your deck to run it doesn’t make it consistent.
Rimescale Dragon: Not in the snow theme to make use of the ability.
Rith, the Awakener: Saplings are nice but not necessary usually.
Rorix Bladewing: Big LEGENDARY vanilla creature. Meh.
Runehorn Hellkite: Don’t like giving opponent cards even if you can do it from your graveyard at instant speed.
Ruthless Deathfang: If we’re sacrificing creatures, it’s usually a bad time for us.
Ryusei, the Falling Star: If this dragon dies, the board is getting wiped which invalidates the wipe attached to him.
Sailors' Bane: Interesting if you're able to run enough effects to make him cheaper but this isn't the deck for it.
Sarkhan's Whelp: Small dragon and requiring a Sarkhan on the field doesn’t make this good.
Sapphire Dragon: Offers some utility in Adventure card but not impactful enough
Savage Ventmaw: Usually used in extra combat combos and only having 2/5 mana requirements for casting cards might not let you cast anything.
Scaled Nurterer: Nice budget mana dork but there are better options.
Scion of Ugin: No.
Scourge of Kher Ridges: Great abilities if you have the mana to use them whenever you need to.
Scourge of Nel Toth: Better in a sacrifice/graveyard deck.
Shieldhide Dragon: Too expensive for a bad body and irrelevant ability.
Shimmer Dragon: Not enough artifacts to give hexproof or draw cards consistently.
Shivan Dragon: OG Vanilla dragon.
Shivan Hellkite: Vanilla pump dragon.
Shockmaw Dragon: Better wiping dragons to kill a mass number of small creatures’ opponents have.
Siege Dragon: Great in a wall/small creature meta.
Silvanus's Invoker: If you're spending 8 mana on this ability, you are losing the game.
Skanos Dragonheart: Needing to swing and have dragons and somehow have this be able to get through is asking a lot.
Skarrgan Hellkite: 10/10 mammoth hat. Too mana intensive of an ability when there’s better things to do instead.
Skithiryx, the Blight Dragon: Multiple combats to kill someone with infect ain’t going to happen.
Skyline Despot: Monarch is a great mechanic, but you’ll instantly become targeted and then find it difficult to grab the monarch back.
Skyship Stalker: Dragon too small and too much pumping required.
Slumbering Dragon: If you don’t play on T1, card gets significantly worse the later in the game you draw it.
Sparktongue Dragon: Too mana intensive cost for an ability to shoot one thing.
Spawn of Thraxes: Not enough mountains/recursion to be able to reuse the ability.
Spellbound Dragon: Anything big worth discarding to pump this dragon enough assuming it doesn’t get chumped only denies us more resources.
Sprite Dragon: Better in a spellslinger type of deck.
Steel Hellkite: There are better mass removal options that don’t require connecting through combat.
Stirring Bard: Interesting ability but there are better ways to ensure dragons can get through in the air.

Stormwing Dragon: Too expensive for a bad body and irrelevant ability.
Sunscorch Regent: Nice life buffer if there are a lot of aggressive decks.
Swasbuckler Extraordinaire: Interesting ability but need enough token producers to sac for double strike as well as there being better cards to give double strike.
Swift Warkite: No/minimal creatures to bring back form graveyard.
Sword Coast Serpent: Not enough non creature spells to reliably swing.
Tanazir Quandrix: No +1/+1 counter synergies in the deck and not able to make a lot of smaller creatures to get an effect out of boosting their base power and toughness.
Tarox Bladewing: Not good in singleton format.
Teeka's Dragon: Too big and expensive to make a big enough impact on the game.
Tek: Weird dragon with a lot of abilities to read so too much effort.
Teneb, the Harvester: Good reanimator but too slow to start reanimating dragons versus what is available.
Territorial Hellkite: The best early aggressor for Dragons but would end up in scenarios of wanting to attack
specific players but unable to.
Terror of Mount Velus: Decent creature if looking for more double striking abilities but one time use seems too situational.
Thunder Dragon: Field wipe not needed as there are better options that only hurt opponents.
Thunderbreak Regent: Single targeted removal wasn’t present enough to justify.
Thundermaw Hellkite: Better in a flying token meta.
Tiamat Fanatics: No way to make use of the tokens and will likely die when it attacks.
Topaz Dragon: Deathtouch for one dragon doesn't matter in a game of EDH.
Treva, the Renewer: Good if lifegain is a necessity. Otherwise, usually irrelevant as you end up with no creatures and a lot of life.
Two-Headed Dragon: Weird interactions for combat but usually not necessary.
Tyrant of Valakut: There are no teammates in Magic and there’s better dragons that deal damage when they enter.
Tyrant's Familiar: We have a 9 cmc general so having both in play at the same time is a challenge for sure.
Vaevictis Asmadi: Pumping himself is irrelevant and having an upkeep cost strains the mana.
Vampiric Dragon: A lot of setup required to have creatures die in order to get counters on him.
Velomachus Lorehold: Better in a build with bigger and more instants and sorceries to have more hits of the ability.
Verix Bladewing: Scales to be played at any point in the game but splitting up threats between bodies isn’t really needed.
Viashivan Dragon: Expensive cost for a bad body.
Volcanic Dragon: Vanilla haste dragon yawn.
Voracious Dragon: Deck doesn’t have goblins nor an abundance of creatures to sacrifice.
Vorosh, the Hunter: Better as a Commander as the ability only helps himself.
Wardscale Dragon: Players can usually ignore this ability and still deal with the board before combat.
Warmonger Hellkite: Funny political card if you’re looking to get other people to start swinging too.
Wasitora, Nekoru Queen: Making people sac creatures was irrelevant as usually you want to get a token off each
combat which won’t always happen.
Worldgorger Dragon: Combo dragon only.
Yosei, the Morning Star: Deterrent for field wiping you but hard to have immediate follow up to punish them for missing their untap.
Young Blue Dragon: Better utility for Limited than EDH.
Young Red Dragon: Not impactful enough of a dragon for EDH.
Zodiac Dragon: Expensive vanilla dragon.
