How it works
Activate Kiki-Jiki by tapping it, creating a token copy of All-Fates Stalker.
When the All-Fates Stalker token enters the battlefield, it triggers, exiling Kiki-Jiki until All-Fates Stalker leaves the battlefield.
Activate Thermopod by sacrificing the All-Fates Stalker token.
When the All-Fates Stalker token dies, Kiki-Jiki is returned from exile to the battlefield.
Repeat.
This loop ingeniously bypasses Kiki-Jiki, Mirror Breaker's usual limitation of sacrificing its copied tokens at the end step by instantly feeding them to Thermopod for red mana instead. When Kiki-Jiki taps to copy All-Fates Stalker, the token's entry trigger exiles Kiki-Jiki to temporarily tuck it away safely. Sacrificing that All-Fates Stalker token to Thermopod then immediately releases Kiki-Jiki back to the battlefield, ready to copy the stalker all over again.
