Madness Manifested

Cards in your hand have Madness {p/b}{p/r}
Whenever a non-token creature enters play under
your control or a creature you control attacks,
you may discard a card at random. If you do, that
creature gains +X/+X until end of turn, where X
is equal to the number of card types among cards
in your graveyard.
