Naru Meha, Master Wizard + Thunderous Debut + Mortuary + Ashnod's Altar

Naru Meha, Master Wizard

Thunderous Debut

Mortuary

Ashnod's Altar

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 Ashnod's Altar by sacrificing Naru Meha, adding CC.
5. When Naru Meha dies, Mortuary triggers, putting Naru Meha on top of your library from your graveyard.
6. 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.
7. Repeat from step 3.

This loop relies on Naru Meha, Master Wizard entering the battlefield to repeatedly copy Thunderous Debut, which is initially cast by paying its cost and bargaining an extra permanent. Thanks to Mortuary waiting patiently in play, whenever Ashnod's Altar converts Naru Meha into a pair of colorless mana, the Wizard is immediately placed right back on top of your library instead of staying in the graveyard. Resolving the copied Thunderous Debut then lets you dig deep into your library to effortlessly pull Naru Meha straight back onto the battlefield, restarting the cycle and fueling an endless loop of sacrifices.
