Kiki-Jiki, Mirror Breaker

Auton Soldier

How it works

1. Activate Kiki-Jiki by tapping it, creating a token copy of Auton Soldier that has haste. Choose to have Auton Soldier enter as a copy of Kiki-Jiki.
2. Put the oldest Kiki-Jiki into the graveyard due to the legend rule.
3. Repeat step 1 using the Auton Soldier token instead.
4. Activate Auton Soldier by tapping it, creating a token copy of itself with haste that will be sacrificed at the next end step.
5. The Auton Soldier token enters the battlefield as a nonlegendary copy of Kiki-Jiki with an additional +1/+1 counter.
6. Activate the Auton Soldier token by tapping it, creating a token copy of itself with haste, exile that token at the end of turn.
7. Repeat from step 2.
