Yarus, Roar of the Old Gods + Karlov Watchdog + Bloodflow Connoisseur + Blim, Comedic Genius

Yarus, Roar of the Old Gods

Karlov Watchdog

Bloodflow Connoisseur

Blim, Comedic Genius

How it works

1. Deal combat damage to an opponent using Blim. Blim triggers, giving control of Karlov Watchdog to an opponent.
2. During the opponent's turn, activate Bloodflow Connoisseur 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 Bloodflow Connoisseur ability.
5. Repeat from step 2.
