Junko Enoshima

When Junko Enoshima enters the battlefield, enemy discards 3 cards at random.
Mastermind - Pay {x} amount of {b}. How much {x} was is how much damage the target takes. You may spread this around however you want.
Monokuma - Pay {w/b}. If you paid {w}, take one card from the graveyard and play it immediately. If {b}, exile one card from target's graveyard.
