How it works
Gain life in any way.
Heroic Feast triggers, putting a +1/+1 counter on Scurry Oak.
Scurry Oak triggers, creating a creature token that enters the battlefield as an artifact due to Mycosynth Lattice.
Teething Wurmlet triggers, causing you to gain life.
Repeat from step 2.
This loop is a masterclass in turning a single instance of life gain into a self-sustaining engine. With Mycosynth Lattice turning every permanent into an artifact, any creature token that enters the battlefield immediately feeds Teething Wurmlet's lifegain trigger, which in turn fuels Heroic Feast to distribute +1/+1 counters. Those counters trigger Scurry Oak to generate a new Squirrel token, restarting the entire cycle and effortlessly pumping out an endless tide of creatures and counters.
