Kiki-Jiki, Mirror Breaker

Grimgrin, Corpse-Born

Lumbering Battlement

How it works

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