Enter the Dungeon

Choose 1:
• Reveal the bottom card of your library. If it is a creature card, you may cast it this turn. If you
do, you may have it fight another target creature
you don't control.
• Sacrifice a creature. If you do, you may reveal
the bottom card of your library. If it is a creature
card, you may cast it this turn. If you do,
it enters the battlefield with a number of +1/+1 counters equal to the sacrificed creature's
toughness.
