Kiki-Jiki, Mirror Breaker + Spawning Pit + Faceless Butcher

Kiki-Jiki, Mirror Breaker

Spawning Pit

Faceless Butcher

How it works

1. Activate Kiki-Jiki by tapping it, creating a token copy of Faceless Butcher.
2. When the Faceless Butcher token enters the battlefield, it triggers, exiling Kiki-Jiki until Faceless Butcher leaves the battlefield.
3. Activate Spawning Pit by sacrificing the Faceless Butcher token.
4. When the Faceless Butcher token dies, Kiki-Jiki is returned from exile to the battlefield.
5. Resolve the Spawning Pit ability.
6. Repeat.
