Vesuvan Serpent

When Vesuvan Serpent comes into play, create a
blue and black creature token that is an exact
copy of another target creature in play. That
target creature's controller loses 3 Life.
{3}{u}{u}: Vesuvan Serpent gains flying and all the abilities of any target creature until end of turn.
{3}{b}{b}: Sacrifice another creature you control to
give Vesuvan Serpent +8/+8 until end of
turn.
