Naru Meha, Master Wizard + Extract from Darkness + Yahenni, Undying Partisan

Naru Meha, Master Wizard

Extract from Darkness

Yahenni, Undying Partisan

How it works

1. Cast Extract from Darkness by paying its mana cost
2. Holding priority, cast Naru Meha by paying its mana cost.
3. When Naru Meha enters, it triggers, targeting Extract from Darkness.
4. Holding priority, activate Yahenni by sacrificing Naru Meha.
5. Resolve the Naru Meha trigger, copying Extract from Darkness
6. Resolve the Extract from Darkness copy, causing each player to mill two cards and returning Naru Meha from your graveyard to the battlefield.
7. Repeat from step 3.

This clever loop sets up an infinite graveyard recursion engine using Extract from Darkness to mill your opponents and pull Naru Meha, Master Wizard straight back from the grave. When Naru Meha enters the battlefield, her triggered ability copies the original spell, creating a continuous stream of copies while leaving a loop-ready target. Meanwhile, Yahenni, Undying Partisan acts as the necessary sacrifice outlet to send Naru Meha back to the graveyard so she can be repeatedly reanimated by each new iteration of the spell.
