Phyrexian Altar + Naru Meha, Master Wizard + Second Sunrise

Phyrexian Altar

Naru Meha, Master Wizard

Second Sunrise

How it works

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

This ingenious loop begins by casting Second Sunrise to prime the battlefield, immediately followed by Naru Meha, Master Wizard, whose entry trigger targets the original spell on the stack. Before that copy resolves, you sacrifice Naru Meha to Phyrexian Altar to generate the mana needed for future iterations while sending the Wizard safely to your graveyard. The resulting copy of Second Sunrise then resolves, bringing Naru Meha right back to the battlefield to repeat the cycle. Because Phyrexian Altar also nets you a mana of any color with every sacrifice, this self-sustaining sequence lets you continuously recur your pieces for infinite colored mana, death triggers, and spell copies.
