Varus

First Strike, Reach
As long as your devotion to {b}{r}{g} is less then
seven, I am not a creature.
For every spell you play a turn, give target
creature you control +1/+0 until end of turn.
Limit Break (Transform me when conditions are met.
I keep all counters when flipped.)A creature you
control has had its power increased by 7+ in one
turn.
