Emiel the Blessed + Agatha of the Vile Cauldron + Wily Goblin

Emiel the Blessed

Agatha of the Vile Cauldron

Wily Goblin

How it works

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

This elegant loop relies on Agatha of the Vile Cauldron to slash Emiel the Blessed's blink activation cost down to just one mana, transforming it into a self-sustaining engine. With that discount locked in, you continuously exile and return Wily Goblin to the battlefield, generating a fresh Treasure token each time it re-enters. You then crack that very same Treasure to pay for the next activation of Emiel the Blessed, allowing you to cycle the Goblin indefinitely for boundless entry and leave-the-battlefield triggers.
