Rosangela, Thorn of the Gods

Flying, lifelink, haste
If another nontoken creature would die, you may
exile that card instead. If you do, put a +1/+1
counter on Rosangela, Thorn of the Gods.
Whenever you gain life, you may pay {2}{b}. If
you do, target creature gets -X/-X until end of
turn, where X is the amount of life you gained.
