Hexproof

{2}{w}{u},{t}: Change the target of target spell or
ability. If there is an instance of increasing or decreasing power and/or toughness in the targeted
spell or ability, you may have it do the opposite. (If
the spell or ability would give +1/+1 to the target, you
may instead have it give -1/-1, and vice versa).
