The Mimeoplasm (EDH / Commander)

The Primary win condition for this deck is by making The Mimeoplasm very large and difficult to deal with.
The main creatures that are used for the +1/+1 counters are;

1) Lord of Extinction, this guy can just produce an absolutely ridiculous amount of +1/+1 counters even if no mill spells had been used just due to the natural build up of the graveyards over the game.

2) Consuming Aberration, this one doesn't get as large as Lord of Extinction because he doesn't look at your own graveyard which in many games will be the largest, but it can still get incredibly large and the tacked on mill effect gives it a larger impact on the game when it is on the battlefield.

3) Death's Shadow and Phyrexian Dreadnought, they are both 1 mana creatures that put themselves directly into the grave yard. Death's Shadow has a distinct advantage because many of the base creatures have a power of 8 which results in The Mimeoplasm having the lethal power of 21.

The primary base creatures in the deck that The Mimeoplasm will enter as a copy of are;

1) Dimir Infiltrator, you can use its transmute ability to reliably get it into the graveyard and put Lightning Greaves into your hand. This will let you have a large, shrouded, hasty, unblockable The Mimeoplasm

Gaea's Revenge, Hydra Omnivore, and Stormtide Leviathan, all of these creatures have the magic power 8 that works so well with Death's Shadow.
2) Gaea's Revenge has haste, is uncounterable and has 4/5ths of shroud which helps to keep it safe.

3) Hydra Omnivore has no form of protection or evasion, but if it gets a clean hit in you should win the game on the spot and all you need is for one of your opponents to have a weak boardstate. Whispersilk Cloak can be used to make it unblockable, Wonder can be used to give it flying, and an overloaded Cyclonic Rift can be used to clear out the board and end the game.

4) Stormtide Leviathan will always be unblockable and it has the added benifit of stopping many of the creatures on the field from attacking while also allowing all of your creatures to still attack if Wonder is in your graveyard.

Some of the other win conditions in this deck are casting Torment of Hailfire for a large X value. Jarad, Golgari Lich Lord can be used to sacrifice a creature like Lord of Extinction to deal a massive amount of damage to all of the opponents. Also Mindcrank combos with Bloodchief Ascension or Duskmantle Guildmage to instantly kill your opponents.

I am looking to help improve the consistency of the deck.
