Ozamatli, God of Hydras

Indestructible, trample, reach
As long as your devotion to red and green is less
than seven, Ozamatli isn't a creature.
Hydra spells you control enter the battlefield
with an additional +1/+1 counter on it.
Ozamatli's power is equal to your devotion to red,
and it's toughness is equal to your devotion to
green.
