Lord Skrolk, Plague-Herald

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 each player end step, if they
were damaged by a Rat they discard a card. Then
if a player has no cards in hand, they lose 10 life.

through Skrolk."
