Darien, King of Kjeldor + Goblin Bombardment + Soul Warden

Darien, King of Kjeldor

Goblin Bombardment

Soul Warden

How it works

1. Activate Goblin Bombardment by sacrificing another creature, dealing 1 damage to yourself.
2. Darien triggers, creating a 1/1 Soldier creature token.
3. When the Soldier enters the battlefield, Soul Warden triggers, causing you to gain 1 life.
4. Repeat.

This clever loop turns self-inflicted pain into an endless army by turning every point of damage into a cascade of resources. You use Goblin Bombardment to ping yourself for one, which immediately prompts Darien, King of Kjeldor to marshal a 1/1 white Soldier token to your defense. That incoming Soldier makes Soul Warden trigger to replace the life you just lost, leaving you free to feed the newly arrived token right back into Goblin Bombardment to restart the cycle.
