Playing with Death

Choose an opponent. Pick a card from their hand
at random, then have them pick a card from your
hand at random. Reveal the selected cards and
compare their mana costs. Whichever player
picked the card with the higher mana cost creates
a 3/3 Grim Reaper token with deathtouch.
Return both cards to your hands.
The Deck of Many Things offers many boons and
many banes.
