Grixis

This is a Grixis Commander midrange/reanimator deck in blue-black-red, built around classic Shards of Alara Grixis themes: unearthed creatures, sacrifice/value plays, removal, and big splashy finishers.

Its main plan is to control the board early with cards like Terminate, Agony Warp, Countersquall, Bituminous Blast, and Fleshbag Marauder, then generate value from creatures with unearth and graveyard recursion, especially Sedris, the Traitor King. Cards like Viscera Dragger, Dregscape Zombie, Grixis Slavedriver, Extractor Demon, and Igneous Pouncer work well with this plan, while Thraximundar, Prince of Thralls, Defiler of Souls, and the various Nicol Bolas cards give the deck powerful top-end threats.

It usually wins by grinding opponents out with removal and discard, then closing the game with large evasive attackers, repeated unearthed threats, or haymakers like Cruel Ultimatum, Nicol Bolas planeswalkers,
