Insanity

If an opponent would draw a card, you draw that
many cards. If an opponent would gain life, you
gain that much
life. if an opponent would discard cards from anywhere, you discard
that many cards.
if an opponent would lose life, you lose that much
life. if an opponent puts any sort of counter on a creature, you put an
identical counter on one of your creatures.
Humanity is only as strong as it believes.
