Joker

When Joker enters the battlefield, put six joke
cards in your and target opponent's deck, then
shuffle. Whenever you or target opponent draw a
joke card, reveal it immediately. If you don't
control Joker, opponent can discard a joke card
and draw another. Otherwise choose an option
that wasn't chosen on all the previous joke cards.
If someone hates you without a reason,
give that jerk a reason
