Create a 3/1 black and red Vampire creature token with
trample (This creature can deal excess combat damage to the player or planeswalker it's attacking.),
lifelink (Damage dealt by the creature also causes its controller to gain that much life.), and
haste (This creature can attack,
and
as soon as it comes under your control.). Sacrifice it at the beginning of the next end step.
