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 Viscera Seer 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 clever loop sets up an infinite engine by leveraging Corpse Dance to continually recur our key wizard from the graveyard. Whenever Corpse Dance is cast, Naru Meha, Master Wizard enters the battlefield to copy it, targeting Corpse Dance back onto the stack while Viscera Seer sits ready to sacrifice Naru Meha to clear the way for the next iteration. Because Corpse Dance brings Naru Meha straight back from the graveyard, the copy targets Naru Meha anew and perpetuates the cycle. This creates infinite sacrifices, death triggers, and scrys, allowing you to dig through your entire deck at instant speed.
