Mairsil the Pretender - Commander

This Grixis colored combo deck is looking to assemble and execute a number of game ending combos revolving around activated abilities and graveyard shenanigans, enabled by Mairsil and his Grixis cohorts.

This is my favorite EDH deck that I’ve built, and I've invested quite a bit of time and effort into the tuning and refining of this list. I really enjoy pushing the limits of what Mairsil can do as a commander, and I'm also willing to recognize his limitations. He's slower and his "I Win" button costs more than most of the other high-power Grixis commanders. Most of his wincons are stretched across 3 or 4 separate cards and are thus more difficult to assemble and far easier to disrupt. Because of this, I've cut the majority of these combos that require a multitude of pieces to work. I've honed in on Mirror-Mad, Tree//Hateflayer, and packages involving Necrotic Ooze, as they remain the most efficient and compact packages that this deck can run. By trimming down these superfluous pieces we can run more interaction and more tutors, providing better consistency and the permission pieces we'll need to go off and win.

Currently testing: + Snapcaster Mage, Red Elemental Blast, Drown in the Loch, Perplex - Fabricate, Walking Ballista, Phyrexian Devourer, Careful Study

Saving up for Vampiric Tutor, Pact of Negation, and Intuition currently

Considering bringing in Worldgorger + Final Parting - Worldgorger loops for infinite mana, we can then cast Mairsil and cage Mogg Fanatic, sac Mairsil to ping for 1 damage and recast and sac until the table dies

List of Mairsil Combos:

Hateflayer + Tree of Perdition: One of the more compact combos that can be grabbed with Buried Alive alongside Aetherling

Laboratory Maniac + Demonic Consultation + Cantrip

Necrotic Ooze + Kiki-Jiki + Mogg Fanatic: Can be done off of the Mirror-Mad combo as an alternative to LabMan, or you can just Buried Alive for all three pieces and then reanimate Necrotic Ooze with Animate Dead or Reanimate

Mirror-Mad Phantasm -> Narcomoeba + Gravecrawler + Fatestitcher -> Dread Return -> Laboratory Maniac -> Deep Analysis/Faithless Looting: (6 mana) After caging Mirror-Mad Phantasm with Mairsil, activate for 1U, shuffling Mairsil into the library and then subsequently putting your entire library into the grave. Narcomoeba enters automatically, and Gravecrawler/Dregscape Zombie can be returned for B. Fatestitcher has Unearth for U as well, and between these you will have enough to flashback Dread Return, returning Laboratory Maniac to the battlefield. Fatestitcher can untap a land or Mana Vault if you need it, and from there Flashback Deep Analysis for 1U and 3 Life, or Faithless Looting for 2R, and win.
