Basking Broodscale + Bloodspore Thrinax + Reyhan, Last of the Abzan

Basking Broodscale

Bloodspore Thrinax

Reyhan, Last of the Abzan

How it works

1. Cast Basking Broodscale by paying 1, causing it to enter with a +1/+1 counter due to Bloodspore Thrinax.
2. When Basking Broodscale enters, it triggers, creating an 0/1 Eldrazi Spawn creature token that enters with a +1/+1 counter due to Bloodspore Thrinax.
3. Activate the Eldrazi Spawn by sacrificing it, adding C.
4. When the Eldrazi Spawn dies, Reyhan triggers, putting at least one +1/+1 counter on Basking Broodscale.
5. Basking Broodscale triggers, creating an 0/1 Eldrazi Spawn creature token that enters with a +1/+1 counter due to Bloodspore Thrinax.
6. Repeat from step 3.
