Hidetsugu and Kairi

How it plays & wins

This is a Dimir (blue-black) reanimator and sacrifice shell built around fast mana like Sol Ring, Mana Vault, Chrome Mox, Lotus Petal and Dark Ritual. Hidetsugu and Kairi digs for gas and fills the graveyard, and the deck leans on recursion such as Rise of the Dark Realms, Beacon of Unrest, Necromantic Selection and No One Left Behind. Sacrifice outlets like Ashnod's Altar, Viscera Seer, Carrion Feeder and Spawning Pit work with Blood Artist to grind value and drain opponents. Flare of Denial offers some protection.

The cleanest win is the Thassa's Oracle package. Demonic Consultation or Tainted Pact empties the library, and Thassa's Oracle then wins on the spot. Tendrils of Agony is another possible finisher, and the drain engine can close out a game that goes long. Beyond those, I can't say with confidence how the other pieces fit together.
