Cast Fake Your Own Death by paying 1, targeting any creature.
Holding priority, cast Naru Meha by paying 2.
When Naru Meha enters the battlefield, it triggers, copying Fake Your Own Death, targeting Naru Meha.
Resolve the copy of Fake Your Own Death.
Holding priority, activate Ashnod's Altar by sacrificing Naru Meha, adding CC.
When Naru Meha dies, it triggers, returning itself from your graveyard to the battlefield and creating a Treasure token.
Repeat from step 3.
This loop sets up an infinite recycling engine by leveraging Naru Meha, Master Wizard's enter-the-battlefield trigger to endlessly duplicate Fake Your Own Death. Once Fake Your Own Death resolves on Naru Meha, sacrificing her to Ashnod's Altar triggers her revival effect, returning her to the battlefield while leaving behind a valuable Treasure token. Because her entry copies the spell once more, you can continuously repeat this cycle to generate boundless mana, tokens, and triggers of all kinds.
