Piercing Witchblade

As Piercing Witchblade enters the battlefield,
choose one —
• Puncture — Excess noncombat damage that
would be dealt to a creature an opponent
controls is dealt to that creature's controller
instead.
• Exit Wound — Whenever 2 or more excess
damage is dealt to a creature an opponent
controls, exile that creature and its controller
discards a card.
