The Mad Stitcher

Ward — Sacrifice a creature and discard a card.

Whenever The Mad Stitcher enters or attacks, mill four cards.

At the beginning of your end step, exile two cards
at random from your graveyard. If two creature
cards are exiled this way, create a token with the
power, toughness, and name of one of those cards
and the colors, abilities, types, and mana cost of
the other.
