Kiki-Jiki, Mirror Breaker + Werefox Bodyguard + Phantom Train

Kiki-Jiki, Mirror Breaker

Werefox Bodyguard

Phantom Train

How it works

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

This clever loop centers around Kiki-Jiki, Mirror Breaker duplicating Werefox Bodyguard to continuously exile and return the Goblin Shaman. Because the newly arrived Werefox Bodyguard token's enter-the-battlefield trigger exiles Kiki-Jiki, you simply need a way to sacrifice the token to bring Kiki-Jiki right back; Phantom Train provides this outlet by consuming the Werefox Bodyguard token while simultaneously growing larger with each iteration. As the token leaves the battlefield, its sacrifice and death triggers cascade infinitely while your army of triggers mounts—all fueled by the transient nature of the copied fox.
