Another card that combos with Scourge of the Skyclaves? Sounds interesting.

(Negative power creatures have a fun property of, well, being negative power when calculating total power. Having a high life total means you can bring back your whole GY as long as you bring back the scourge too.)

This is just the indatha ultimatum, but single colored.

Edit: Nevermind, I confused it with the mutate a tan creature. Nethroi.
