Fabrication Module + Aetherstorm Roc + Scurry Oak

Fabrication Module

Aetherstorm Roc

Scurry Oak

How it works

1. Cast Scurry Oak by paying its mana cost.
2. When Scurry Oak enters, Aetherstorm Roc triggers, causing you to get E.
3. Fabrication Module triggers, putting a +1/+1 counter on Scurry Oak
4. Scurry Oak triggers, creating a creature token.
5. When the creature token enters, Aetherstorm Roc triggers, causing you to get E.
6. Repeat from step 3.

This brilliant loop turns a simple creature entry into a self-sustaining engine of growth and swarming tokens. It all kicks off when Aetherstorm Roc passively watches the battlefield, converting every single creature entry—including the initial Scurry Oak and each token it produces—into a steady stream of energy counters. Fabrication Module acts as the crucial translator, immediately taking that generated energy and turning it into +1/+1 counters on Scurry Oak. Those counters then trigger Scurry Oak's own ability to birth a 1/1 green Squirrel creature token, which in turn feeds right back into Aetherstorm Roc to keep the cycle spinning infinitely.
