Naru Meha, Master Wizard + Phantom Train + Vincent's Limit Break

Naru Meha, Master Wizard

Phantom Train

Vincent's Limit Break

How it works

1. Cast Vincent's Limit Break by paying its mana cost.
2. Holding priority, cast Naru Meha by paying its mana cost.
3. When Naru Meha enters, it triggers, copying Vincent's Limit Break, with the copy targeting Naru Meha.
4. Resolve the copy of Vincent's Limit Break.
5. Holding priority, activate Phantom Train by sacrificing Naru Meha.
6. When Naru Meha dies, it triggers, returning it from your graveyard to the battlefield.
7. Repeat from step 3.
8. Resolve all Phantom Train abilities from step 5.

This clever loop turns Naru Meha, Master Wizard into a self-replicating engine by combining her enter-the-battlefield spell-copying ability with Vincent's Limit Break. When Naru Meha enters the battlefield, she copies Vincent's Limit Break to target herself, granting her an undying-style return trigger when she dies. You can then sacrifice her to Phantom Train's activation cost, putting a +1/+1 counter on the Vehicle while sending Naru Meha to the graveyard so her new trigger brings her straight back to repeat the entire process.
