Kiki-Jiki, Mirror Breaker + Ashnod's Altar + All-Fates Stalker

Kiki-Jiki, Mirror Breaker

Ashnod's Altar

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 Ashnod's Altar 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. Repeat.
