Ward—Discard a card, Deathtouch

Whenever an opponent discards a card:
• Creature- create a 2/2 black Rat creature token.
• Land card- create a treasure token.
• Noncreature- nonland card, draw a card.

At the beginning of your end step, if an opponent
was damaged by a rat, they discard a card, then if a player has no cards in hand, they lose 10 life.
