Cast Vincent's Limit Break by paying its mana cost.
Holding priority, cast Naru Meha by paying its mana cost.
When Naru Meha enters, it triggers, copying Vincent's Limit Break, with the copy targeting Naru Meha.
Resolve the copy of Vincent's Limit Break.
Holding priority, activate Phyrexian Altar by sacrificing Naru Meha.
When Naru Meha dies, it triggers, returning it from your graveyard to the battlefield.
Repeat from step 3.
This clever loop turns the flexibility of Vincent's Limit Break into an engine for infinite mana and triggers. By casting the spell and then responding with Naru Meha, Master Wizard, you set up an ETB trigger that copies Vincent's Limit Break right back onto Naru Meha itself, granting the wizard a delayed return-to-the-battlefield trigger when it dies. You then sacrifice Naru Meha to Phyrexian Altar to generate any color of mana, triggering its own undying-style resurrection effect and sending it right back to the battlefield to restart the cycle.
