Fantastic Charm

({p/u} can be paid with either {u} or 2 life.)
Gain control of target Non-Human creature until
end of turn. Untap it. It gains haste until end of turn.
If that creature deals damage to its owner
on this turn, you may pay {2}, if you do,
gain control of that creature until that creature dies.
"My philosophy is
that worrying means you suffer twice."
