Scurry Oak + Thunder of Unity + The Destined White Mage

Scurry Oak

Thunder of Unity

The Destined White Mage

How it works

1. Gain life.
2. The Destined White Mage triggers, putting a +1/+1 counter on Scurry Oak.
3. Scurry Oak triggers, creating a creature token.
4. When the creature token enters the battlefield, Thunder of Unity triggers, causing you to gain 1 life and each opponent to lose 1 life.
5. Repeat from step 2.

This loop turns a simple spark of life into an unstoppable engine by creating a closed feedback loop among three distinct permanents. Once you initiate it, The Destined White Mage responds to your life gain by dropping a +1/+1 counter onto Scurry Oak, which then triggers to pop out a fresh Squirrel token. That token's arrival on the battlefield wakes up Thunder of Unity, whose chapter abilities immediately siphon life from your opponents and hand it right back to you, fueling The Destined White Mage all over again.
