Leyline of Vitality + Sunbond + Scurry Oak

Leyline of Vitality

Sunbond

Scurry Oak

How it works

1. Gain life.
2. Sunbond triggers, putting a +1/+1 counter on Scurry Oak.
3. Scurry Oak triggers, creating a creature token.
4. When the creature token enters the battlefield, Leyline of Vitality triggers, causing you to gain 1 life.
5. Repeat from step 2.

This delightful loop spins entirely out of a single initial life gain trigger, which causes Sunbond to pump up Scurry Oak with +1/+1 counters. Because Scurry Oak triggers whenever those counters are placed upon it, it immediately spawns a 1/1 green Squirrel creature token to swell your ranks. That new token entering the battlefield then awakens Leyline of Vitality, whose passive presence turns every creature's arrival into the exact life gain needed to restart Sunbond all over again.
