Naru Meha, Master Wizard + Carrion Feeder + Black Sun's Twilight

Naru Meha, Master Wizard

Carrion Feeder

Black Sun's Twilight

How it works

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

This infinite loop is sparked by casting Black Sun's Twilight with enough mana to unlock its resurrection clause, setting the stage for Naru Meha, Master Wizard to enter the fray and copy the spell on the stack. By utilizing Carrion Feeder as a convenient sacrifice outlet, you send Naru Meha straight to the graveyard so the copied Black Sun's Twilight can immediately bring her right back to the battlefield. This recursive cycle endlessly recasts and copies the spell while feeding a growing tower of +1/+1 counters to Carrion Feeder with every iteration.
