How I Built Mimsy: My Mimeoplasm Self-Mill EDH Deck

My Mimeoplasm EDH deck: Mimsy, to the pod, is built on one idea: mill my own library as fast as possible, then assemble a game-ending commander from the wreckage. It is not a goodstuff pile and it is not trying to steal your creatures. Every ooze it becomes was placed in my graveyard on purpose.

I'll be honest up front, because that's the only way I evaluate decks: this one is 4-25 across 29 recorded games. I'm going to tell you why I built it anyway, what actually works, and what the losses taught me.

Most Mimeoplasm decks I'd seen treated the commander as an opportunist that copies whatever the table's graveyards happen to offer. That never appealed to me. If my commander's power level depends on what my opponents played, I don't control my own consistency, and consistency is the whole game in Commander.

So the build constraint was set from day one: The Mimeoplasm copies my creatures. That means the deck's real job is stocking my graveyard with hand-picked bodies, and the commander is just the delivery mechanism. For , he exiles two creature cards from graveyards, enters as a copy of one, and picks up +1/+1 counters equal to the other's power. Both halves of that equation are deckbuilding decisions if you let them be.

The early versions leaned on generic self-mill, and it was too random. The deck got dramatically better when I shifted the slots toward selective graveyard-filling — tutors that put exactly the right creature exactly where I want it.

Buried Alive is the MVP: three creatures of my choice, straight to the graveyard, one card. Entomb and Unmarked Grave do the single-target version, and Survival of the Fittest is a repeatable machine that both finds creatures and ditches them. Hermit Druid is the reason I run only nine basic lands — with so few basics to hit, each activation mills a serious chunk of my library.

Around that core sits the volume mill: Mesmeric Orb, Altar of Dementia, Titans' Nest turning dead cards into mana, and Icetill Explorer pulling milled lands back into play. The measured curve backs the plan up — 35 lands, 3.49 average mana value, and a role count that's heavy on draw and tutors and deliberately light on everything else.

The fun of the deck is the target suite, and every pick is doing a specific job.

Vorinclex, Monstrous Raider is the ceiling: haste, plus every counter placed on Mimsy is doubled. Tyrranax Rex is the ideal second exile — huge power for the counter side, and as a base it brings haste, trample, toxic, and protection. Ukkima, Stalking Shadow is the sneaky one: unblockable, and opponents genuinely don't want to kill it because of the death trigger. Yargle and Multani exists purely to be the biggest number in the graveyard. Skithiryx, the Blight Dragon gives me a flying infect line, and Lord of Extinction scales with every graveyard at the table.

There's also a plan Z: Laboratory Maniac. In a deck that mills itself this aggressively, an "empty library wins" clause is real insurance — and in one recorded game it was the actual win, with Phyrexian Metamorph copying him and Titans' Nest fueling the final turns.

When it works, it's genuinely violent. In one game this May I landed a turn-4 kill with a 22/22 haste-trample Mimsy with Vorinclex, Monstrous Raider as the base, and Tyrranax Rex adding sixteen doubled counters. That's the deck's thesis executed perfectly.

But 4-25 is 4-25, and I don't hide from numbers. Reading back through the game logs, the pattern is clear: my pod has gotten fast. Multiple recent losses were turn-3 and turn-4 combo kills, and a voltron deck that needs setup turns before its first swing simply doesn't get them in that environment. The deck's failure mode isn't the engine, it's that a 21-damage plan against one player at a time is slow math in a pod that wins all at once.

That's fixable, and it's the next chapter: more cheap interaction, fewer luxuries. For now, here's exactly where the list landed, and the record, in full, because the losses are part of the story.
