Deeptide Growth

When Deeptide Growth enters the
battlefeild, if it's green, untap target land. If
it's three or more colors, instead draw a card.
At the beginning of your upkeep, put a
+1/+1 counter on target blue creature you
control. You gain 2 life and add {g/u}. (When
adding {g/u}, add either {u} or {g}.)
