Ghave, Guru of Spores + Basking Broodscale + Doubling Season

Ghave, Guru of Spores

Basking Broodscale

Doubling Season

How it works

1. Activate Ghave's second ability by paying 1 and sacrificing another creature, putting two +1/+1 counters on Basking Broodscale.
2. Basking Broodscale triggers, creating two 0/1 Eldrazi Spawn creature tokens.
3. Activate an Eldrazi Spawn by sacrificing it, adding C.
4. Repeat.

This loop thrives on the multiplicative engine of Doubling Season, which turns every single counter placed and token created into a doubled surplus. When you sacrifice a creature to fuel Ghave, Guru of Spores, those sacrifices feed into Basking Broodscale, whose adapt trigger and +1/+1 counter generation are instantly doubled by Doubling Season to spit out extra Eldrazi Spawn tokens. Those very Eldrazi Spawn can then be sacrificed for mana to pay for Ghave's ability, sustaining the infinite cycle while continuously piling up counters and triggers.
