Arwen Undómiel + Sylvan Anthem + Scurry Oak

Arwen Undómiel

Sylvan Anthem

Scurry Oak

How it works

1. Cause a green creature to enter the battlefield under your control.
2. Sylvan Anthem triggers, causing you to scry 1.
3. Arwen Undómiel triggers, putting a +1/+1 counter on Scurry Oak.
4. Scurry Oak triggers, creating a 1/1 Squirrel creature token.
5. Repeat from step 2.

This loop turns any green creature entering the battlefield into an endless cascade of triggers, propelled by Sylvan Anthem's passive scry ability whenever a green creature enters. That scry immediately awakens Arwen Undómiel, whose triggered ability places a +1/+1 counter onto Scurry Oak. Because Scurry Oak responds to any counters placed on it by spawning a 1/1 Squirrel token, its own token creation feeds back into Sylvan Anthem, keeping the cycle spinning infinitely to generate boundless creature tokens, scry 1s, and massive stats.
