Darien, King of Kjeldor + Pandemonium + Angel's Grace

Darien, King of Kjeldor

Pandemonium

Angel's Grace

How it works

1. Cast Angel's Grace by paying .
2. Cause a creature to enter the battlefield under your control.
3. Pandemonium triggers, dealing damage to you equal to the creature's power, with your life total becoming no lower than 1 due to Angel's Grace.
4. Darien triggers, creating a number of 1/1 Soldier creature tokens equal to the damage dealt to you.
5. When the Soldiers enter the battlefield, Pandemonium triggers that many times.
6. Resolve the first trigger, dealing 1 damage to you, with your life total becoming no lower than 1 due to Angel's Grace.
7. Repeat from step 3.

This loop is a masterclass in self-sustaining synergy, kicked off by casting Angel's Grace to ensure that the damage you take can never actually drop your life total below one. Once that safety net is active, a creature entering the battlefield triggers Pandemonium to deal damage to you, which in turn awakens Darien, King of Kjeldor to flood your board with 1/1 Soldier tokens in response to the pain. Those very same incoming Soldiers trigger Pandemonium all over again upon entry, creating a continuous feedback loop of damage and reinforcements that safely generates infinite creature tokens and enters-the-battlefield triggers.
