I agree about removing Spellbook. I also think Reliquary Tower should be removed. I made a deck very similar to this one and I found that having no maximum hand size would have hurt me in some situations. I love your draw and discard spells to put some important cards from your hand to your graveyard. You can also put those cards into your graveyard by going over your maximum hand size so Spellbook and Reliquary Tower are counter productive. Maybe some green staples as replacement. How about Tooth and Nail to get Mikaeus, the Unhallowed and Triskelion? And mana ramp is always helpful, perhaps Green Sun's Zenith to tutor for a Hermit Druid or Satyr Wayfinder?Another issue I ran into was not enough islands for Wonder to activate. I think I'm going to remove some guild gates and Reliquary Tower to fix that.I think a card you should definitely add is Lightning Greaves. This makes The Mimeoplasm so much more deadly. Blighted Agent or Phyrexian Crusader or any other really powerful creature can be a one turn win instead of a two turn win. Contagion Clasp and Contagion Engine should also be considered for removal. I found myself only using infect to swing for wins rather than doing some poison damage and proliferating to increase it. The infect combos seem to be much to fast to make use of these cards. There are probably better options as replacements.Here are some cards that may be considered (some are more staples than synergy):Vampiric Tutor,Mystical Tutor,Rune-Scarred Demon,Sepulchral Primordial,Mimic Vat,Tezzeret the Seeker ,Phyrexian Arena,

Sorry, my formatting is awful. Your deck is awesome, keep on keepin' on.

Ah 2 other thoughts.Kruphix, God of Horizons removed for same reason about maximum hand size. Tooth and Nail can be used to put any 2 creatures in the graveyard for The Mimeoplasm if you go over the maximum hand size! Combos!

thanks guys ! I'll buy the cards soon and edit the deck later ! Thanks :)

it may be valid to consider effects like Dictate of Erebos or Grave Pact since you are pitching a lot of your creatures. This being said, if a lot of your pitching comes from Entomb effects it may not be worth it

thanks for the suggestions guys ! I've considered all of them and have just edited the deck and some of the description !!

Just some tiny things, but you could replace Farseek and Explosive Vegetation with Nature's Lore and Skyshroud Claim, as they can pull out Breeding Pool and Overgrown Tomb (or just some Forests), untapped!

just a curious question, but why the three artifact lands? Am I missing a synergy?

Prophet of Kruphix is banned now :(

Wouldn't using Woodfall Primus in the mill combos make them not truly infinite? You need to destroy a permanent every time you loop the combo, and therefore unless there are enough non-creature permanents to get through your opponents' decks, then you will eventually have to destroy your own Altar of Dementia?

dalton342, with the "destroy target noncreature permanent" trigger on the stack, you can sac Woodfall Primus to Altar of Dementia in response. You can still go infinite, but if you don't get the win, you will have to deal with all of those "destroy target noncreature" triggers. But typically, if you have a way to infinitely sac Woodfall Primus people will just scoop after you nuke their lands.

With the introdution of Ixalan now a lot of Commanders have dinossaurs :(

But your deck continues incredible!

+1!

Hey not sure if you're still playing this deck but Prophet of Kruphix is banned in EDH

I think a great addition to this deck would be Varolz, the Scar-Striped because of cards like Phyrexian Dreadnought and Death's Shadow . They are all pretty great together.

Hey this is an awesome deck! I have a similar deck build, and just wanted to share another wincon - Palinchron & Deadeye Navigator, have Laboratory Maniac out, play Guardian Project - you mill yourself out from Guardian Project because Palinchron keeps hitting the battlefield and take the win!
