Split second

Target creature or planeswalker an opponent controls gains “at the beginning of the next player’s upkeep, exile this card.” If you own that creature or planeswalker, it gains “at the beginning of the next player’s upkeep, exile this card, then return it to the battlefield under its owner’s control. It’s a legendary enchantment and loses all other card types. You gain 5 life.” Then it phases out.
