Cast Vincent's Limit Break by paying its mana cost.
Holding priority, cast Naru Meha by paying its mana cost.
When Naru Meha enters, it triggers, copying Vincent's Limit Break, with the copy targeting Naru Meha.
Resolve the copy of Vincent's Limit Break.
Holding priority, activate Altar of Dementia by sacrificing Naru Meha.
When Naru Meha dies, it triggers, returning it from your graveyard to the battlefield.
Repeat from step 3.
Resolve all Altar of Dementia abilities from step 5.
This clever loop spins up by casting Vincent's Limit Break to set up a resilient creature, then dropping Naru Meha, Master Wizard into play with flash to intercept the spell's copy trigger. By copying Vincent's Limit Break to target Naru Meha itself, the Wizard gains a permanent "dies-and-returns" trigger that effortlessly sidesteps traditional removal. Whenever Naru Meha's newfound rebirth magic threatens to leave the battlefield, you simply feed it to Altar of Dementia; the sacrifice sends Naru Meha straight to the graveyard only to immediately snap back to the battlefield, triggering another copy of Vincent's Limit Break in an endless, mill-fueled cycle.
