Yarus, Roar of the Old Gods + Karlov Watchdog + Viscera Seer + Donate

Yarus, Roar of the Old Gods

Karlov Watchdog

Viscera Seer

Donate

How it works

1. Cast Donate by paying its mana cost, giving control of Karlov Watchdog to an opponent.
2. During the opponent's turn, activate Viscera Seer by sacrificing a face-down creature you control.
3. When the creature dies, Yarus's second ability triggers, returning it from your graveyard to the battlefield face-down as a 2/2 creature, and then not turning it face-up due to Karlov Watchdog.
4. Resolve the Viscera Seer ability.
5. Repeat from step 2.
