Stolen Essence

Must be cast by a Vampire Creature
After paying cost, play this card face-down until
the beginning of the Battle Phase; then flip it
face-up. When flipped face up, target one
non-Vampire / Machina Creature on the field.
Reduce all of that Creature's stats by 50%; add
the stats that were lost to the stats of the
Creature who cast this Sorcery until the end of
the round.
