Naru Meha, Master Wizard + Yahenni, Undying Partisan + Stir the Grave

Naru Meha, Master Wizard

Yahenni, Undying Partisan

Stir the Grave

How it works

1. Cast Stir the Grave by paying 4.
2. Holding priority, cast Naru Meha by paying its mana cost.
3. When Naru Meha enters, it triggers, targeting Stir the Grave.
4. Holding priority, activate Yahenni by sacrificing Naru Meha.
5. Resolve the Naru Meha trigger, copying Stir the Grave
6. Resolve the Stir the Grave copy, returning Naru Meha from your graveyard to the battlefield.
7. Repeat from step 3.

This clever loop puts Yahenni, Undying Partisan at the center of a self-sustaining cycle by using its own sacrifice ability to feed a recursive engine. When you cast Stir the Grave with enough mana to target Naru Meha, Master Wizard in your graveyard, you can flash in Naru Meha to copy the spell on entry. Before the copy resolves, Yahenni sacrifices Naru Meha, sending it back to the graveyard so the copied Stir the Grave can resurrect it all over again.
