Whimsy, Broken Broker

At the beginning of your upkeep, you may create
Mopsy, a legendary 0/1 black cat creature token
with "Sacrifice this creature. Search your library
for a card with mana value equal to its power,
then shuffle."
When Whimsy, Broken Broker deals combat
damage to a player, draw a card.
