Gwen

First Strike, Hallowed (When I am in your
graveyard, I give target creature +1/+0 during
combat.)
If other creatures you control are gaining power
from Hallowed creatures in your graveyard, I gain
the same amount of power.
Limit Break (Transform me when conditions are met.
I keep all counters when flipped.) I have dealt 10+
damage in a turn.
