Yarus, Roar of the Old Gods + Karlov Watchdog + Goblin Bombardment + Fateful Handoff

Yarus, Roar of the Old Gods

Karlov Watchdog

Goblin Bombardment

Fateful Handoff

How it works

1. Cast Fateful Handoff by paying its mana cost, giving control of Karlov Watchdog to an opponent.
2. During the opponent's turn, activate Goblin Bombardment 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 Goblin Bombardment ability.
5. Repeat from step 2.
