Holding priority, cast Naru Meha by paying its mana cost.
When Naru Meha enters, it triggers, copying Undying Malice, with the copy targeting Naru Meha.
Resolve the copy of Undying Malice.
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 harnesses the recursive safety net of Undying Malice to set up an eternal cycle of rebirth for Naru Meha, Master Wizard. Every time Naru Meha re-enters the battlefield thanks to that spell's delayed trigger, its enter-the-battlefield ability goes on the stack to copy Undying Malice right back onto itself, ensuring you can endlessly sacrifice it to Altar of Dementia. Because Altar of Dementia mills your opponents every single time Naru Meha is sent to the graveyard, this continuous loop quickly digs through an entire deck to win the game on the spot.
