Meira, Clearwater Druid

Whenever you activate a creature's mana ability,
you may pay {1}. If you do, put a +1/+1 on Meira,
Clearwater Druid.
Druid creatures you control have "{t}: Add {g} or {u}" and "{t}: Move a +1/+1 counter from
this creature onto another target creature. That creature becomes a Druid in addition to its other
types."
The water knows the will of the woods.
