Niphark, seeker of truth

Ravenous
Flying, trample
Niphark isn't a creature if your devotion to red,
green and black is 10 or less.
Whenever you cast a creature spell you may pay {x}, if you do the creature enters the battlefield
with X +1/+1 counters on it and it gains hexproof until end of turn.
Creatures you control with counters on them have haste and menace.
