Varina, Aggro Queen (EDH / Commander)

This deck is pretty simple, play a lot of cheap zombies and play Varina on Turn 4, then start cranking her loot ability.

Sacrifice outlets allow for a big combat step followed by sacing all creatures and then playing a Living Death to drain out opponents with entering-the-battlefield drain effects or "whenever a creature dies" effects via Wayward Servant, Corpse Knight, or Plague Belcher.

A full graveyard recursion package includes Relentless Dead, Eternal Taskmaster, The Scarab God, Emry, Lurker of the Loch, Hall of Heliod's Generosity, Elixir of Immortality, Crypt of Agadeem, Witch's Cottage and Mystic Sanctuary.

Rooftop Storm + Gravecrawler + sacrifice outlet (Carrion Feeder or Phyrexian Altar) and a Wayward Servant, Corpse Knight or Plague Belcher = infinite damage triggers and a win outright.

Graveyard protection is needed in this deck so we have Elixir of Immortality, Lazotep Plating and Teferi's Protection to avoid spells and abilities that ruin our day.

Vanquisher's Banner + Rooftop Storm or Bolas' Citadel can refill our hand and rebuild after a board wipe.

This deck has nearly no ramp because the goal is to play 2-3 zombies before playing Varina. Echo Storm is meant to copy other players' mana rocks to help catch up and Bolas' Citadel is a way to rebuild your board if you get all your creatures exiled.

Gray Merchant of Asphodel + Rite of Replication is an almost sure-fire way to close out the game (Gary + Rite is 40 damage to all opponents with no other black pips on the board) but Rite of Replication is a great way of keeping in the game if an opponent's board gets out of control. Rite can also be used on many of our cheap zombies to great effect (5 Wayward Servants, 5 Plague Belchers, 5 Rotting Regisaurs, etc).
