The 4 combo pieces

What must be in place

You control a face-down creature whose front face is a permanent card.

How to execute it

  1. Activate Zedruu by paying {U}{R}{W}, giving control of Karlov Watchdog to an opponent.
  2. During the opponent's turn, activate Blasting Station by tapping it and 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. When the creature enters the battlefield, Blasting Station triggers, untapping Blasting Station.
  5. Resolve the Blasting Station ability from step 2.
  6. Repeat from step 2.
