Kiki-Jiki, Mirror Breaker + Altar of Dementia + All-Fates Stalker

Kiki-Jiki, Mirror Breaker

Altar of Dementia

All-Fates Stalker

How it works

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

This brilliant loop hinges on a clever temporary-exile trick using Kiki-Jiki, Mirror Breaker to continuously duplicate All-Fates Stalker. Every time the token copy enters the battlefield, its triggered ability tucks away Kiki-Jiki, effectively resetting the goblin and letting Altar of Dementia safely sacrifice the token before the end step demands it. As the token dies to mill away your opponent's library, Kiki-Jiki drops right back onto the battlefield ready to repeat the cycle.
