Cast Corpse Dance 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 Corpse Dance.
Holding priority, activate Umbral Collar Zealot by sacrificing Naru Meha.
Resolve the Naru Meha trigger, copying Corpse Dance, with the copy targeting Naru Meha
Resolve the Corpse Dance copy, returning Naru Meha from your graveyard to the battlefield.
Repeat from step 3.
This elegant loop uses Corpse Dance to pull Naru Meha, Master Wizard from your graveyard, immediately triggering its ability to copy the original spell and retarget the wizard. Umbral Collar Zealot acts as the sacrificial engine that sends Naru Meha back to the graveyard to fuel the cycle, turning its sacrifice into a steady stream of surveil triggers while continuously reviving your wizard. Because Corpse Dance uses buyback or can be endlessly recopied depending on the stack management, this choreography generates infinite enter-the-battlefield, death, and sacrifice triggers to overwhelm your opponents.
