Joker's Insanity reads: "+1 Power

Defense: You may discard this card to avoid an Attack. If you do, draw a card."

That means that Insanity only adds 1 Power when played regularly, the same as a Punch. However, if Insanity is in your hand when an Attack or FIRST APPEARANCE--Attack is launched against you, you have the option to defend with Insanity by discarding it, and then drawing one card.
