Mikaeus, the Unhallowed grants undying to non-Humans, letting Blood Pet and companions die twice per loop; Ashnod's Altar converts those deaths into the colorless mana needed to cast Rise of the Dark Realms, which reassembles every piece and resets the counters. Eternal Witness recurs Rise of the Dark Realms each loop, keeping the engine self-contained. The combo lives in reanimator and sacrifice shells — Meren of Clan Nel Toth and Jarad, Golgari Lich Lord are the natural homes.

Variations

Cheaper, tighter, alternate lines

The fifth slot filled by Eternal Witness is the most swappable — any non-Human with an enters-the-battlefield recursion effect that returns Rise of the Dark Realms from the graveyard can close the loop. Cut the combo down to a tighter Mikaeus line by substituting Persist creatures like Kitchen Finks alongside Grumgully, the Generous if the Rise package feels too mana-intensive; the five-card version wins the game outright when it resolves, but assembling nine mana before a wrath ends everything.
