When Madame Masque enters, she connives. (Draw a card, then discard a card. If you discarded a nonland card, put a +1/+1 counter on this creature.) Whenever you draw your second card each turn, create a 2/1 black Villain creature token with menace. (It can't be blocked except by two or more creatures.)
