8 rulings from Wizards of the Coast
- 24 January 2025If you copy a double-faced creature card with Soul Separator’s ability, the resulting Spirit token will be a double-faced token. The listed exceptions will apply to both the front and back faces of the Spirit token. The Zombie token will not be a double-faced token.
- 24 January 2025The Spirit token will be on the battlefield before the Zombie token enters.
- 24 January 2025The Spirit token has the color and mana cost (and thus mana value) of the original card; the Zombie token has a mana value of 0.
- 24 January 2025The power and toughness of the Zombie token are set as it’s created based on the card as it last existed in your graveyard. They won’t update if the exiled card’s power and toughness change.
- 24 January 2025If the copied creature card has an ability that defines its power and toughness, such as that of Sage of Ancient Lore, the Spirit token will still have base power and toughness 1/1.
- 24 January 2025Abilities that define a creature’s power and toughness apply while that card is in your graveyard, but abilities that add or subtract from it don’t. For example, the ability of Sage of Ancient Lore applies to determine the Zombie token’s power and toughness, but the ability of Liliana’s Elite doesn’t.
- 24 January 2025Any “enters” abilities of the copied creature card will trigger when the Spirit token enters. Any “as [this creature] enters” or “[this creature] enters with” abilities of the creature card will also work.
- 24 January 2025If the copied creature card has {X} in its mana cost, X is considered to be 0.
