Melora, the Wildmother

Melora costs {x} less to cast, where X is the total
power of creatures you control.
At the beginning of your upkeep, create a 3/3
green beast creature token, then choose one:
- Draw a card. You may play an additional land
this turn.
- Until end of turn, target creature gets +1/+0
and gains first strike, haste and trample.
