Kaya's Ghostform

If Kaya’s Ghostform enchants a permanent you control but don’t own, that permanent will return to the battlefield under your control when it dies or is exiled. In a multiplayer game, if a player leaves the game, all cards that player owns leave as well. If you leave the game, any creatures you control from Kaya’s Ghostform’s effect are exiled.

Kaya’s Ghostform is put into your graveyard once the enchanted permanent leaves the battlefield. It doesn’t return to the battlefield with that permanent.

Kaya’s Ghostform can enchant a token, but its last ability won’t return the token to the battlefield.
