Treebeard, Gracious Host + Scurry Oak + Trostani, Selesnya's Voice

Treebeard, Gracious Host

Scurry Oak

Trostani, Selesnya's Voice

How it works

1. Gain life.
2. Treebeard's second ability triggers, putting that many +1/+1 counters on Scurry Oak.
3. Scurry Oak triggers, creating a 1/1 Squirrel creature token.
4. When the Squirrel enters the battlefield, Trostani triggers, causing you to gain life.
5. Repeat from step 2.

This loop is a masterclass in synergistic living, turning a simple burst of life into an unstoppable engine of nature's growth. Once you kick things off, Scurry Oak serves as the centerpiece that constantly spits out Squirrel tokens, which in turn trigger Trostani, Selesnya's Voice to swell your life total. That newly gained life immediately feeds Treebeard, Gracious Host, whose passive trigger responds by slapping +1/+1 counters right back onto Scurry Oak. That influx of counters restarts Scurry Oak's own token-generating cascade, locking the whole table into an unbroken, self-sustaining cycle of infinite life, counters, and furry little creatures.
