The Nightmare

Can't be blocked.
When The Nightmare comes on the battlefield,
put a dream counter on two or more of the
opponent's creatures. Only creatures with a
dream counter can block and be blocked by The Nightmare. If there are one or fewer dream
counters in play, put new ones on a creature an opponent controls.
