Naru Meha, Master Wizard + Yahenni, Undying Partisan + Return to Action

Naru Meha, Master Wizard

Yahenni, Undying Partisan

Return to Action

How it works

1. Cast Return to Action by paying its mana cost.
2. Holding priority, cast Naru Meha by paying its mana cost.
3. When Naru Meha enters, it triggers, copying Return to Action, with the copy targeting Naru Meha.
4. Resolve the copy of Return to Action.
5. Holding priority, activate Yahenni by sacrificing Naru Meha.
6. When Naru Meha dies, it triggers, returning it from your graveyard to the battlefield.
7. Repeat from step 3.
8. Resolve all Yahenni abilities from step 5.

This clever loop turns a simple recursion spell into a perpetual engine by pairing the copy effect of Naru Meha, Master Wizard with the instant-speed sacrifice outlet provided by Yahenni, Undying Partisan. When you cast Return to Action targeting Naru Meha and hold priority to flash in the Wizard over top of it, Naru Meha enters the battlefield and copies the original instant to keep the chain alive. By using Yahenni to sacrifice Naru Meha in response, you trigger the "return to the battlefield" effect granted by Return to Action—and because Naru Meha enters fresh every single time, it endlessly re-copies the spell to generate infinite sacrifice and death triggers.
