Reincarnation + Naru Meha, Master Wizard + Bloodflow Connoisseur

Reincarnation

Naru Meha, Master Wizard

Bloodflow Connoisseur

How it works

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

This clever loop hinges on Reincarnation targeting Naru Meha, Master Wizard, which is kept safe from permanent death by its own delayed return trigger. As Naru Meha enters the battlefield repeatedly to copy the original spell, Bloodflow Connoisseur provides the crucial sacrifice outlet needed to send the Wizard back to the graveyard to restart the chain. Because Naru Meha continually reincarnates and feeds the Connoisseur, you can repeat the process as many times as you like to generate infinite death triggers, enter-the-battlefield effects, and a massively growing +1/+1 counter total.
