Trapped by Sleep

Enchant Creature
When Trapped by Sleep enters the battlefield,
tap enchanted creature and put 3 stun counters
on it.
At the beginning of enchanted creature's
controller's upkeep, that player loses life equal to
3 minus the number of stun counters on
enchanted creature. Then, if there are no stun counters on enchanted creature, sacrifice
Trapped by Sleep and draw a card.
