Kiki-Jiki, Mirror Breaker + Spawning Pit + Hostage Taker

Kiki-Jiki, Mirror Breaker

Spawning Pit

Hostage Taker

How it works

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