Ghave, Guru of Spores + Illusionist's Bracers + Berta, Wise Extrapolator + Scurry Oak

Ghave, Guru of Spores

Illusionist's Bracers

Berta, Wise Extrapolator

Scurry Oak

How it works

1. Activate Ghave's second ability by paying 1 and sacrificing another creature, targeting Scurry Oak
2. Illusionist's Bracers triggers, copying Ghave's ability, targeting Berta.
3. Resolve the first Ghave ability, putting a +1/+1 counter on Berta.
4. Berta triggers, adding 1.
5. Resolve the second Ghave ability, putting a +1/+1 counter on Scurry Oak.
6. Scurry Oak triggers, creating a creature token.
7. Repeat.

This loop turns Ghave, Guru of Spores into a self-sustaining engine by outfitting him with Illusionist's Bracers, allowing his sacrifice ability to trigger twice for a single payment. When you sacrifice a creature to put a counter on Berta, Wise Extrapolator, Berta's triggered ability generates the mana needed to fuel the next activation while simultaneously buffing Scurry Oak. That resulting counter on Scurry Oak triggers its ability to spit out a Squirrel token, providing a fresh body to sacrifice to Ghave and keeping the infinite cycle of counters, deaths, and ETBs spinning endlessly.
