Vessel of Vintor

When Vessel of Vintor enters the battlefield, you
may have it become an artifact creature until end
of turn. If you don't, create three 1/1 black
Vampire creature tokens with lifelink instead.
Whenever Vessel of Vintor attacks, create a
Vampire token. Then Vampires you control
become Bats in addition to their other types
and gain flying and haste until your next turn.
