Essence Flux

Exile target creature you control, then return that card to the battlefield under its owner's control. If it's a Spirit, put a +1/+1 counter on it.

Shadows over Innistrad Remastered

A spirit is both fettered and free—bound in some ways to its previous existence, yet able to transcend much of the corporeal.

Jumpstart

Shadows over Innistrad

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.

Essence Flux checks whether the creature is a Spirit after it has returned from exile.

If a creature token is exiled, it ceases to exist. It won’t be returned to the battlefield.

If a double-faced card is exiled, it will return with its front face up.
