Emiel the Blessed + Plundering Barbarian + Agatha of the Vile Cauldron

Emiel the Blessed

Plundering Barbarian

Agatha of the Vile Cauldron

How it works

1. Activate Emiel the Blessed by paying 1, blinking Plundering Barbarian.
2. When Plundering Barbarian enters the battlefield, it triggers, creating a Treasure artifact token.
3. Activate the Treasure by tapping and sacrificing it, adding 1.
4. Repeat.

This loop relies on Agatha of the Vile Cauldron to act as a crucial cost reducer, lowering the activation cost of Emiel the Blessed's blink ability so that it matches the single mana produced by Plundering Barbarian. When you exile Plundering Barbarian and return it to the battlefield, its enters-the-battlefield trigger allows you to create a Treasure token. You then crack that Treasure to generate the mana needed to repeat the process with Emiel the Blessed, netting an infinite number of creature leaves-the-battlefield and enters-the-battlefield triggers.
