The Ooze + Basking Broodscale + Juniper Order Ranger

The Ooze

Basking Broodscale

Juniper Order Ranger

How it works

1. Cast Basking Broodscale by paying 1.
2. When Basking Broodscale enters, Juniper Order Ranger triggers, putting a +1/+1 counter on it and Basking Broodscale.
3. Basking Broodscale triggers, creating a 0/1 Eldrazi Spawn creature token.
4. When the Eldrazi Spawn enters, Juniper Order Ranger triggers, putting a +1/+1 counter on it and the Eldrazi Spawn.
5. Activate the Eldrazi Spawn by sacrificing it, adding C.
6. When the Eldrazi Spawn dies, The Ooze triggers, creating a Mutagen token.
7. Activate the Mutagen by paying 1, tapping and sacrificing it, putting a +1/+1 counter on Basking Broodscale.
8. Repeat from step 3.
