LANDSBlood Crypt, Overgrown Tomb, & Stomping Ground- The shock lands in these colors, I put the shock lands in every multicolored deck, they're fectable and come in untapped at a very little price.
Bloodstained Mire, Verdant Catacombs, & Wooded Foothills- Unforutanly Verdant Catacombs is real expensive, but the other two are reasonably priced, oh yeah, always play fetch lands.
Bojuka Bog- Play it in every deck, it is the only graveyard hate in this deck.
Cinder Glade &
Smoldering Marsh
- Luckily Jund isn't a wedge color so we get two BFZ lands, they're great, fectchable, cheap price wise, and usually come in untapped.
Command Tower- Goes in every multi-colored commander deck.
Dragonskull Summit, Rootbound Crag, & Woodland Cemetery- Check lands, usually always come in untapped, and cheap price wise, they're usually always in my multi-colored decks.
Evolving Wilds & Terramorphic Expanse- I put these in every multi-colored deck, although they are pretty crappy in super competitive metas.
Exotic Orchard & Reflecting Pool- Both are usually just another Command Tower.
Forest 10, Mountain 3, & Swamp 3- A good chunk of basics to get w/ my ramp.
Grim Backwoods
- Sacrifice a Kobold to draw a card, there isn't much card draw, so it's nice to have a way to draw cards on a land, even though it costs a lot of mana.
High Market- Used to sacrifice Prossh when you want more Kobolds and have no other way to sacrifice him.
Mana Confluence- A solid mana fixer.
Savage Lands
- You should usually play the tri lands in 3-colored decks, I wouldn't play this in a super competitive meta though.
Urborg, Tomb of Yawgmoth- Goes in every multicolored deck that runs .
Westvale Abbey
- Can transform after you cast Prossh once, then it becomes a real nasty beater that is hard to deal w/.
PLANESWALKERS
Sarkhan Vol
- All 3 abilities are fantastic in this deck. The +1 gives Prossh haste, which is incredibly powerful and gives haste to the Kobolds to attack or tap for mana using Cryptolith Rite. His -2 steals an opponents creature that you can sacrifice once you're done w/ it. His -6 puts 20 damage worth of dragons on the field.
Vraska the Unseen- She's in here for her -3 to deal w/ nonland permeants, mostly enchantments & artifacts.
Xenagos, the Reveler- Getting 7+ mana w/ his +1 is just stupid, one of the best ramp cards in the deck. His +1 almost feels like an ultimate in this deck.
INSTANTS
Chord of Calling- Convoke the Kobolds to get an OP creature, usually Sidisi, Undead Vizier to get an OP non-creature card or convoke to get Craterhoof Behemoth if you have enough untapped Kobolds.
Nature's Claim- A very efficient enchantment/artifact destroyer.
Pyroblast- Protection from counterspells, mostly to protect key cards like Food Chain.
Vampiric Tutor- Get the appropriate ramp early game, or get a combo piece you need, usually Food Chain.
CREATURES
Avenger of Zendikar- The "mini-Prossh", works similar to Prossh, so it benefits from many of the same synergies and it's nice having redundancy in the deck.
Blood Artist & Zulaport Cutthroat- They're great in any sacrifice deck that runs , but incredibly powerful in this deck, can be used as a finisher w/ infinite Kobolds and a sacrifice outlet.
Butcher of Malakir- A constant one-sided board wipe, if your opponent's can't answer this card and are playing a deck that uses creature to do much of anything (like most decks), they will lose rather quickly.
Craterhoof Behemoth- The mother of all finishers in creature decks, he's especially good in this deck usually having the team swing in for around 500 damage, also great w/ infinite Kobolds.
Deathbringer Thoctar- W/ 1 counter, he can kill everything w/ 1 toughness on the field (don't forget the Kobolds, yes sometimes you will want to kill them to trigger dying effects), another instant win card w/ infinite Kobolos & sacrifice outlet.
Dragon Broodmother- Yet another mini-Prossh, makes sacrifice fodder and a way to sacrifice, triggers on each player's turn.
Dragonlair Spider
- A
Forgotten Ancient
for tokens, more sacrifice fodder, you'll usually get 2-6 of them each round around the table.
Goblin Sharpshooter- Another instant win w/ infinite Kobolds & a sacrifice outlet, punishes your opponents for removing creatures, like Deahtbringer Thoctar, you can kill everything w/ 1 toughness including your Kobolds.
Mazirek, Kraul Death Priest- Just by sacrificing a few chump blockers, you can get an army of powerhouses and a huge Prossh.
Ogre Battledriver- Gives Prossh and the Kobolds haste and a power boost allowing them to swing for 19+.
Pathbreaker Ibex- Craterhoof's little brother, a lot better w/ haste, the team will usually swing for 48+ or pump Prossh up to 11 power and kill w/ 22 commander damage.
Purphoros, God of the Forge- Just summoning Prossh for 6 mana you'll do 7x2=14 damage to each opponent, summon Prossh again for 8 mana then you'll be doing 9x2=18 damage, bringing the total to 14+18=32 damage to each opponent just by summoning your commander. Purphoros is amazing in most decks, but he's at his best in Prossh, also auto-win w/ infinite Kobolds.
Sadistic Hypnotist- Get rid of all the cards in your opponent's hands, that is just stupid, and pretty mean.
Sidisi, Undead Vizier- Tutor on a creature, turn that Kobold into a Food Chain.
Skullmulcher- Draw your whole deck w/ infinite Kobolds or just draw a bunch of cards normally, great for this deck and it's a little card draw.
ENCHANTMENTS
Awakening Zone- Ramps and provides sacrifice fodder.
Beastmaster Ascension- Summon Prossh for 6 get 6 Kobolds, attack w/ the team get 7 counters do (5+5)(5x6)=40 damage, just perfect damage, beautiful.
Cryptolith Rite- Makes Prossh infinite comobos easy, especially good when you can give your creatures haste.
Dictate of Erebos- Another Grave Pact effect that is basically a one-sided board wipe, I play it over Grave Pact, because the is a little too difficult to get.
Doubling Season & Parallel Lives- Get 2x the Kobolds making infinite combos easier.
Evolutionary Leap- One of my favorite cards that have been printed recently, turns those dumb Kobolds into excellent creatures.
Food Chain- The most well recognized combos in commander, just summon Prossh w/ Food Chain on the field then you'll get infinite Kobolds and then win w/ the butt load of ways to win w/ infinite Kobolds.
Goblin Bombardment- One of the best sacrifice outlet cards ever printed, 0 mana to start sniping creatures or just punishing your opponents for wiping the board, yet another win condition w/ infinite Kobolds.
Mana Echoes- Summoning Prossh for 6cmc nets you 6x6+1=37 mana, you'll probably win if you have Skullclamp out.
Shivan Harvest
- Gives you another option for attack, destroying your opponent's land.
Sylvan Library- Goes in just about every deck that runs , really helps you get what you need in the beginning of the game, mostly ramp.
SORCERY
Blasphemous Act- One board wipe, yeah I'll take it, goes in just about every deck that runs .
Crux of Fate- Sac all you guys to Prossh, kill all the other creatures on the field and swing in for a bunch.
Cultivate & Kodama's Reach- Excellent ramp spells.
Damnation- Just another board wipe, REPRINT THIS WAY TOO EXPENSIVE CARD WIZARDS! (Biggest fail in recent magic history, Damnation not being printed in from the vault annihilation, a product that really needed a money card.)
Demonic Tutor- One of the best cards in commander, goes in every deck that runs .
Explosive Vegetation & Skyshroud Claim- Ramps into perfect Prossh mana at 6.
Farseek & Nature's Lore- 2 mana ramp that can get shock lands or BFZ lands.
Hull Breach- The Return to Dust for , I put Return to Dust in every deck that runs , so I figured I'd do the same for Hull Breach for .
Nissa's Expedition
- Convoke the Kobolds to insure you can summon Prossh again if he gets removed.
Overwhelming Stampede
- Either pump Prossh up to 11 power to swing for 22 commander damage, or swing w/ an army of pumped up Kobolds.
Search for Tomorrow- An excellent turn 1 play, will usually assure a turn 3-4 Prossh.
Toxic Deluge- A powerful board wipe for this deck, since you can just sacrifice everything that is going to get killed.
ARTIFACT
Ashnod's Altar- Can easily go infinite w/ Phyrexian Altar or Cryptolith Rite + haste, this card even without going infinite nets you a ton of mana.
Basalt Monolith- Gives me mana so I can put down Prossh the turn after I play this.
Helm of Possession- Sacrifice a Kobold to get one of your opponent's creatures, then sacrifice the creature and start the process over again.
Lightning Greaves & Swiftfoot Boots- Gives protection and haste to your commander, both go in just about every commander deck that uses their commander.
Mana Vault- Can get Prossh out turn 3 easily.
Phyrexian Altar- Another good combo piece, makes infinite Kobolds w/ Ashnod's Altar & also w/ Mana Echoes.
Skullclamp- One of the best card draw spells in the deck.
Sol Ring- It's commander.
Trading Post- Another sacrifice outlet that does a crap ton of stuff.
