Naru Meha, Master Wizard + Yahenni, Undying Partisan + Prison Break

Naru Meha, Master Wizard

Yahenni, Undying Partisan

Prison Break

How it works

1. Cast Prison Break either from your hand by paying 4 or from your graveyard for its mayhem cost by paying 3, targeting any applicable target.
2. Holding priority, cast Naru Meha by paying its mana cost.
3. When Naru Meha enters, it triggers, targeting Prison Break.
4. Holding priority, activate Yahenni by sacrificing Naru Meha.
5. Resolve the Naru Meha trigger, copying Prison Break, with the copy targeting Naru Meha
6. Resolve the Prison Break copy, returning Naru Meha from your graveyard to the battlefield.
7. Repeat from step 3.

This clever loop centers around Naru Meha, Master Wizard entering the battlefield to copy spells, specifically targeting Prison Break to continuously resurrect Naru Meha from the graveyard. While the Prison Break copy handles the recursion, Yahenni, Undying Partisan acts as the necessary sacrifice outlet to put Naru Meha back into the graveyard in the first place. Because Yahenni, Undying Partisan can sacrifice Naru Meha at instant speed, you can repeat this cycle endlessly to generate infinite entry, exit, and sacrifice triggers.
