Rule 111.11

If an effect instructs a player to create a token by name, doesn’t define any other characteristics for that token, and the name is not one of the types in the list of predefined tokens above, that player uses the card with that name in the Oracle card reference to determine the characteristics of that token. Example: Disa the Restless has the ability “Whenever one or more creatures you control deal combat damage to a player, create a Tarmogoyf token.” As that ability resolves, its controller creates a token with the same characteristics as the card named Tarmogoyf, as determined by the Oracle card reference.
