Kiki-Jiki, Mirror Breaker + Goatnapper + Arcane Adaptation

Kiki-Jiki, Mirror Breaker

Goatnapper

Arcane Adaptation

How it works

1. Activate Kiki-Jiki by tapping it, creating a token copy of Goatnapper with haste.
2. The Goatnapper token enters the battlefield, untapping Kiki-Jiki.
3. Repeat.

This clever loop transforms Kiki-Jiki, Mirror Breaker into a self-contained engine by rewriting the rules of the battlefield with Arcane Adaptation. By naming "Goat" as the chosen creature type, Arcane Adaptation ensures that every token created is recognized as a Goat alongside its other types. This is the crucial secret that makes Goatnapper's enters-the-battlefield trigger point directly back at Kiki-Jiki, untapping the legendary goblin shaman so the process can repeat indefinitely for an arbitrary number of hasty token copies and entry triggers.
