Phyrexian Altar + Naru Meha, Master Wizard + Prison Break

Phyrexian Altar

Naru Meha, Master Wizard

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 Phyrexian Altar 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 begins when you cast Prison Break to target any applicable creature card in your graveyard, fueling your strategy with the mayhem cost if you discarded it that turn. You then flash in Naru Meha, Master Wizard, whose enters-the-battlefield ability puts a copy of Prison Break on the stack targeting Naru Meha herself. By sacrificing Naru Meha to Phyrexian Altar in response, you generate a colored mana and send her back to the graveyard just in time for the resolving copy of Prison Break to return her straight to the battlefield, ready to repeat the process indefinitely for infinite sacrifice and magecraft triggers.
