Exile target creature. At the beginning of the next end step, return that card to the battlefield under its owner's control with a +1/+1 counter on it.
At the time the creature is exiled, Auras attached to it will be put into their owners’ graveyards. Any Equipment will become unattached and remain on the battlefield. Any counters on it at that time will cease to exist.
If a creature token is exiled this way, it will cease to exist and won’t return to the battlefield.
If a double-faced card is exiled this way, it’ll return with its front face up. It gets a +1/+1 counter even if it isn’t a creature.
If a melded permanent is exiled this way, the two cards will both return with their front faces up. Each gets a +1/+1 counter.
If that creature is exiled during an end step, it won’t come back until the next turn’s end step.
