Cast Incarnation Technique by paying its mana cost, targeting any applicable target.
Holding priority, cast Naru Meha by paying its mana cost.
When Naru Meha enters, it triggers, targeting Incarnation Technique.
Holding priority, activate Ashnod's Altar by sacrificing Naru Meha.
Resolve the Naru Meha trigger, copying Incarnation Technique, with the copy targeting Naru Meha
Resolve the Incarnation Technique copy, returning Naru Meha from your graveyard to the battlefield.
Repeat from step 3.
This clever loop sets up an infinite recursive engine by leveraging Incarnation Technique alongside Naru Meha, Master Wizard. When you cast Incarnation Technique and hold priority to flash in Naru Meha, its enter-the-battlefield ability targets the original spell, allowing you to copy it. You then sacrifice Naru Meha to Ashnod's Altar for colorless mana before the copy resolves, sending the Wizard to the graveyard so the resulting copy of Incarnation Technique can immediately pull her right back to the battlefield. Because Naru Meha re-triggers upon her return to copy the spell again, you can repeat this cycle indefinitely to mill your entire library, generate infinite mana, and trigger endless enter-the-battlefield and death events.
