Cubo Gelatinoso

Auras attached to the exiled creature will be put into their owners' graveyards. Any Equipment will become unattached and remain on the battlefield. Any counters on the exiled creature will cease to exist. When the card returns to the battlefield, it will be a new object with no connection to the card that was exiled.

If Gelatinous Cube leaves the battlefield before its Engulf ability resolves, the target non-Ooze creature won't be exiled.

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

If the engulfed creature card leaves exile, perhaps because of the Dissolve ability, it won't return to the battlefield after Gelatinous Cube leaves the battlefield.
