Yawgmoth, Thran Physician

Scurry Oak

Verdant Sun's Avatar

How it works

1. Cast Yawgmoth by paying 2.
2. When Yawgmoth enters the battlefield, Verdant Sun's Avatar and Scurry Oak's evolve ability trigger.
3. Holding priority, activate Yawgmoth by paying 1 life and sacrificing a creature, putting a -1/-1 counter on Scurry Oak and causing you to draw a card.
4. Resolve the Verdant Sun's Avatar trigger, causing you to gain life equal to Yawgmoth's toughness.
5. Resolve the Scurry Oak trigger, putting a +1/+1 counter on it, triggering Scurry Oak's second ability.
6. Holding priority, activate Yawgmoth by paying 1 life and sacrificing a creature, putting a -1/-1 counter on Scurry Oak and causing you to draw a card.
7. Resolve the Scurry Oak trigger, creating a 1/1 Squirrel creature token.
8. When the Squirrel enters the battlefield, Verdant Sun's Avatar and Scurry Oak's evolve ability trigger.
9. Resolve the Verdant Sun's Avatar trigger, causing you to gain 1 life.
10. Repeat from step 5.

This engine turns life and counters into a self-sustaining loop by letting Scurry Oak and Yawgmoth, Thran Physician feed each other indefinitely. Every time Yawgmoth sacrifices a creature to draw a card and place a -1/-1 counter, Scurry Oak responds to the counter by spawning a Squirrel token, which resets its own evolve trigger while simultaneously fueling Verdant Sun's Avatar to effortlessly offset the life payment. The result is a brilliantly balanced life-gain and draw machine that endlessly recycles your board state.
