Strike of Summer

Put a +1/+1 counter on target creature you
control. It then deals damage equal to its power
to target creature you don't control. Other
creatures you control get +1/+1 until end of turn.
Until end of turn, you can't lose Season counters.
You gain a Summer counter.
In the midst of battle, the ferocity of a Summran
warrior is matched only by the fury of the sun itself.
