Kiki-Jiki, Mirror Breaker

Fiend Hunter

Yahenni, Undying Partisan

How it works

1. Activate Kiki-Jiki by tapping it, creating a token copy of Fiend Hunter.
2. When the Fiend Hunter token enters the battlefield, it triggers, exiling Kiki-Jiki until Fiend Hunter leaves the battlefield.
3. Activate Yahenni by sacrificing the Fiend Hunter token.
4. When the Fiend Hunter token dies, it triggers, returning Kiki-Jiki from exile to the battlefield.
5. Resolve the Yahenni ability.
6. Repeat.
