An Equipment that's also a creature can't be attached to anything. You can activate its equip ability, but it won't become attached.

An artifact creature card or enchantment creature card returned this way will have base power and toughness 1/1.

If a double-faced card is exiled this way, it will return with its front face up, no matter which face was up when it left the battlefield.

If a token is exiled this way, it ceases to exist and won't return to the battlefield.

If another effect causes one of the returned permanents to become a creature and sets its base power and toughness as it does so, that creature will have that power and toughness; it won't be 1/1. Notably, crewing a Vehicle does not set its power and toughness, so a Vehicle will remain a 1/1 if you crew it.

The exiled card will return to the battlefield at the beginning of the next end step even if Abuelo, Ancestral Echo is no longer on the battlefield at that time.
