Yawgmoth, Thran Physician + Scurry Oak + Ajani's Welcome

Yawgmoth, Thran Physician

Scurry Oak

Ajani's Welcome

How it works

1. Cast Yawgmoth by paying 2.
2. When Yawgmoth enters the battlefield, Ajani's Welcome 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 Ajani's Welcome trigger, causing you to gain 1 life.
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, Ajani's Welcome and Scurry Oak's evolve ability trigger.
9. Repeat from step 4.

This elegant engine turns a simple exchange of life into an endless loop of creation and sacrifice, using Scurry Oak to continuously feed fodder to Yawgmoth, Thran Physician. Every time a Squirrel token appears, it triggers Ajani's Welcome to replenish the life you paid to Yawgmoth's activation cost, ensuring you never run out of fuel. The interaction between Scurry Oak and Yawgmoth cancels out their respective counters while drawing you through your entire deck, flooding the board with near-infinite resources.
