Willow, Graveyard Bard

Lifelink, Ward {3}
If an opponent would target a spell that you have
cast, instead return that spell to your hand and
gain life equal to the converted mana cost of the
spell.
If the spell returned this way has a converted
mana cost of 4 or greater the opponent
loses that much life.
