Kiki-Jiki, Mirror Breaker + Blasting Station + Lumbering Battlement

Kiki-Jiki, Mirror Breaker

Blasting Station

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 and Blasting Station trigger.
3. Resolve the Blasting Station trigger, untapping it.
4. Resolve the Lumbering Battlement trigger, exiling Kiki-Jiki until Lumbering Battlement leaves the battlefield.
5. Activate Blasting Station by sacrificing the Lumbering Battlement token.
6. When the Lumbering Battlement token dies, Kiki-Jiki is returned from exile to the battlefield.
7. When Kiki-Jiki enters, Blasting Station triggers, untapping Blasting Station.
8. Resolve the Blasting Station ability from step 5.
9. Repeat.

This loop relies on an ingenious custody exchange between Kiki-Jiki, Mirror Breaker and Lumbering Battlement, where the latter's entry triggers neatly swallows our goblin shaman into exile until it leaves. To keep the cycle spinning, Blasting Station acts as both the executioner and the spring-loaded reset button, constantly untapping itself every time a creature enters the battlefield. As you sacrifice the Lumbering Battlement token to ping your opponents, the exiled Kiki-Jiki is unchained just in time to remake the giant beast anew, establishing an endless loop of collateral damage.
