Bantriel, Dutiful Archangel

Flying, Vigilance, Lifelink
Exalted (Whenever a creature you control attacks
alone, that creature gets +1/+1 until end of turn.)
If a spell or ability you control would cause a
creature to get +1/+1 until end of turn, instead
put a +1/+1 counter on that creature and create
a 1/1 white bird creature token with flying.

"When the gods return to Alycadium, so too will my
lost siblings who have fallen so far from the light.
Until then, I stand watch."
