Doornroosje

When Doornroosje enters the battlefield, choose
target creature to fall asleep. They become tapped
and can't be untapped next turn.

If Doornroosje stays on the field for 10 turns, she
wakes up, gaining 2 +1/+1 counters.

"The princess will not die, but will sleep for a
hundred years." And so it happened.
