Naru Meha, Master Wizard + Thunderous Debut + Mortuary + Altar of Dementia

Naru Meha, Master Wizard

Thunderous Debut

Mortuary

Altar of Dementia

How it works

1. Cast Thunderous Debut by paying 6 and sacrificing an artifact, enchantment or token.
2. Holding priority, cast Naru Meha by paying 2.
3. When Naru Meha enters the battlefield, it triggers, copying Thunderous Debut.
4. Activate Altar of Dementia by sacrificing Naru Meha.
5. When Naru Meha dies, Mortuary triggers, putting Naru Meha on top of your library from your graveyard.
6. Resolve the Altar of Dementia ability, causing target player to mill cards equal to Naru Meha's power.
7. Resolve the copy of Thunderous Debut, causing you to look at the top twenty cards of your library and put Naru Meha and up to one other creature card onto the battlefield.
8. Repeat from step 3.

This clever loop starts by casting Thunderous Debut with its bargain cost paid, letting you set up the top of your library while flashing in Naru Meha, Master Wizard to copy the spell on entry. When Naru Meha is sacrificed to Altar of Dementia, the resulting death triggers Mortuary to place Naru Meha right back on top of your library instead of the graveyard. Meanwhile, the copied Thunderous Debut resolves to pull Naru Meha and another creature straight back onto the battlefield, ready to repeat the entire cycle.
