Ialai, God of Beauty

+1: Untap target land. It becomes a 3/3 Elemental creature with trample and haste until your next turn. It's still a land.
0: Target creature you control gets +X/+X until end of turn, where X is equal to your devotion to blue and green.
-7: Return all nonland permanents you don't control to their owners' hands. You may put a permanent from your hand onto the battlefield.
