Auras attached to the exiled creature will be put into their owners' graveyards. Equipment attached to the exiled creature will become unattached and remain on the battlefield. Any counters on the exiled creature will cease to exist. Once the exiled permanent returns, it's considered a new object with no relation to the object that it was.
When Ennis enters, exile up to one other target creature you control. Return that card to the battlefield under its owner's control at the beginning of the next end step.
At the beginning of your end step, if one or more cards were put into exile this turn, put a +1/+1 counter on Ennis.
Since copies of prepare spells aren't cards, they won't count for Ennis's last ability.
