I would say more ramp, and more draw. Skyshroud Claim , Kodama's Reach , Simic Signet , Rhystic Study , Staff of Nin , or Mind's Eye they could all help you out.

I would also remove the merfolk folks. Couple of buffs to so few are not really worth it. Seedborn Muse , Murkfiend Liege are good adds too.

Peregrine Drake , and Palinchron are 2 more ways to go infinite with Deadeye. Blue Sun's Zenith , or Rocket Launcher for the win.

I think that my comments are really just things that relate to card choices when building competitive decks.

I don't know that I would play so many of the cards like Elvish Mystic in a multiplayer competitive game when you have options like Simic Signet which are better for mana fixing and a bit harder for your opponents to remove. In the games that I play, someone is playing an effect like Wrath of God almost every turn which makes these guys pretty bad.

If you are not caring about your budget as well, I would switch one of those guys out for Rofellos, Llanowar Emissary . My play group is really competitive and for them Gaea's Cradle would also be an auto include for a competitive deck of this nature.

I would also think about replacing Familiar's Ruse with Counterspell in a competitive deck since it seems too situational to get it to go off optimally. I also wouldn't play Farseek in this deck. Your choices for it are really limited to Island and Breeding Pool . If you don't care about fetching the Breeding Pool I would replace it with Sakura-Tribe Elder since it can hit for a few points of damage when you don't need to ramp anymore. If you want to fetch the Breeding Pool with it, I would suggest Nature's Lore instead since it doesn't force it to come in tapped. If you really like that card I would in the very least switch out the Rampant Growth with the Sakura-Tribe Elder .

Since you like some chaos cards, depending on what type of chaos you want to do with the deck, your deck might also benefit from something like Gilder Bairn or Vorel of the Hull Clade which you could activate in response to your commander's draw effect going on the stack to draw even more cards or pump something else, like a planeswalker, to silly proportions.

@Andydw

While Gaea's Cradle is a liiiiiiitle out of my budget, rofellos is well within it, I'll pick one up.

Simic Signet should be in there, I think I replaced it with something on accident XD Familiar's Ruse tends not to have a problem going off, and I'm probably gonna run it in addition to Counterspell (Also should be in there o.o), although I might take it out for more Unsummon effects. Perhaps Call to Heel .

I'll probably swap Farseek with the Nature's Lore , and a land for the elder.

Thanks for the advise

@Digeridooda The merfolk aren't just buffs, they're half this deck's combo potential, for 2 reasons. 1. They enable zegana to come in with larger numbers (a single coralhelm commander makes zegana come in as a 6/6, plus draw 2 more for each other merfolk lord), and 2. They enable Marrow Reejay's combo with Doubling Cube , as prime speaker zegana is rarely enough to go off. I tried Seedborn Muse , but it's just too slow, hell Prophet of Kruphix is about to be cut and it lets me use my bullshit hand size better. In my casual build, however, the card is amazing, the one where it's more durdle-y, and less combo. Peregrine Drake will probably replace the prophet, just because going into a "free" creature with Birthing Pod is my favorite play in this game. If I go infinite with deadeye, I don't need a X spell to win, becasue I cast Zegana, infinite blink her untill I draw a laboratory maniac and plenty of counterspells, and then draw my deck.

Thanks for the comments :)

Also, Mind Sculptor is going in here when I get him in a few days.

I am trying to come with any suggestions but truth to be told, I can't really come with any. I'd quite literally hate to play against this deck. There are of course a few cards but I can't come with any suggestion for what to replace them with. But at least I'll bring them to your attention.

Rewind , Through the Breach , Skyshroud Claim , Three Visits , Sylvan Library , Mirri's Guile , Sensei's Divining Top , Deadwood Treefolk , Bane of Progress , Krosan Grip , Pattern of Rebirth , Scavenging Ooze , Seedborn Muse , Woodfall Primus , Keiga, the Tide Star , Mana Drain

I've since added a few cards, this is an old decklist, before I decided fuck it, I want the deck to win at all costs. No money for stuff like liberary and top, but from your list I've added Skyshroud Claim, Krosan Grip, Seedborn Muse, and I've been considering scooze but I'm getting mixed results.

Thanks for the praise :D this deck is my pet project for a few months, after a fellow spike told me that zegana is unplayable as a commander. I have since proved him wrong, and I'm confident going into the EDH tournament this weekend.

Think I should update the list?

You are making me cry out of fear. There just is so much good synergy and at the same time most cards alone do a pretty big impact on the battlefield once they hit it.

Would be nice with an updated list yeah. Good luck with the tournament and please prove that Spike wrong!

I already have :D This deck has already paid itself back in tournament winnings from little 30/40 tournaments. Updating the list now.

What I do need for suggestions on the deck are silver bullets to deal with meta decks. Stuff like Thrun, the Last Troll for control decks, cards I can search with fauna shaman, green sun's zenith, or chord of calling

Deck is now updated to my build I plan to take this weekend.

Cyclonic Rift can help against Thrun.

Steel Hellkite can offer nice non-targeted control but is much better with haste.

Glaring Spotlight could do the trick, but isn't great otherwise unless you are massing creatures.

Archetype of Endurance works too, you just need a way to get it out. I use it in Damia where I can get it out a few different ways.

Aphetto Alchemist would probably serve you better than Voltaic Key

Voltaic Key doesn't have summoning sickness, which is big when I'm drawing my deck and need that last 20 or 30 mana for a lethal blue sun zenith. I considered the alchemist in addition, but found the redundancy unnecessary. Plus the key can be fetched with tezzy.

Only reason rift isn't in here is I can't find one at my locals. Chrome Mox ? No problem. Mana Vault ? No problem. Dollar rare out of a recent set? Nowhere to be found.

In the spirit of Archetype of Endurance , perhaps Asceticism . It can't be fetched as easily but regen and not being a creature is huge.

Oh, and for the thrun comment, I mean I need cards like that to deal with specific decks. I might put in thrun in my deck to fetch with a green sun for something control can't deal with, without a sweeper. Which I can easily counter.

Just out of curiosity, how often do you benefit from Exploration ? I assume you don't always get it your opening hand, so what I'm really curious about is how it helps you deck later on.

As for a few suggestion. Bane of Progress is a good artifact/enchantment boardwipe that you can have in your sideboard. Easily fetchable since it's a creature.

Burgeoning could be powerful to have in your deck allowing you to outramp your opponent.

Sure Harrow is great but Through the Breach and Kodama's Reach could be better.

I was going to suggest replacing AEther Adept but most likely a dumb idea since it's one of two cards with 3 cmc.

Spellskite is another good sideboard card to deal with typical voltron deck.

Good luck with your tournament!

Exploration is actually not in there for the first turn play. It's in there because when I go off, being able to drop the nykthos (or Gaea's Cradle , when I get one) for some extra mana for doubling cube, as well as a Reliquary Tower , in case something goes wrong, is extremely useful. That's the only reason it's in here will while burgeoning was cut, because while Burgeoning is only good early game, Exploration is great early and late game.

I've thought about Bane of Progress , I'll test it out for sure

I'm assuming you mean a different card other than Through the Breach XD Harrow is a meta call over cultivate/reach, there is a LOT of land destruction in my meta, so being able to turn that destroyed land into 2 new ones at instant speed is usually enough of a tempo play for me to start creeping ahead (or blow them out next turn.) But normally yeah, cultivates would be better.

there aren't enough good 3drops in my colors :/ Maybe Trygon Predator ? eh, I have bad experience with the card, it gets removed more often than not, I'd rather have an ETB trigger. If a good 3drop comes to mind feel free to link it

Spellskite is a good suggestion, I'll add it to the side. Horay for being tezzeret searchable!

I have literally NO idea why I suggested Through the Breach , I meant to suggest Search for Tomorrow . I guess the picture fooled me, it really does look like something comming out of a breach.

And I'm not suggesting to replace AEther Adept , it has a use and has a cmc where it's a bit thin making it a bit more valuable.

Maybe there's a place for Edric, Spymaster of Trest ? He is after all only banned as a commander. There's also a few other great 3 CMC creatures like Fierce Empath , Reclamation Sage and Vendilion Clique

And again, I'd like to point out that you're the one who knows the deck and knows best what it needs when it comes to cards

I tested edric with less than no sucess. My deck runs so few creatures, and him without an exasive creature is kinda... underwhelming.

HOWEVER

Fierce Empath searches for Deadeye Navigator or palichron, or if I can't combo, Frost Titan . Reclamation Sage is a solid sideboard card for the deck, I'll add it. and if I could afford a v-clique this deck would be so much better ;-; Imagine this with cradles, fetches, ect.. fun :D But I will definitely test the empath, my only problem with it is it doesn't do much on it's own, but if it works how I'm thinking, that will be a small concern

Search for tomorrow feels like a mediocre rampant growth tbh, and rampant growth is already the worst ramp spell that made the deck.

Oh, and a fun little interaction with aether adept that should be pointed out (other than with deadeye navigator, that's borderline abusive) is it can bounce my own zegana for more stupid plays. It's come in hand before to a little extra draw

How about Declaration of Naught to piss some people off?

It's just not good enough. Sure it can neutralize a commander, but that's all it can do (or shadowborn apostles). Basically, it does what Hinder or Spell Crumple already do, but doesn't have the option of countering other things. Plus spell crumple and hinder can't be Naturalize d.

You never have problems running only 30 lands?
