Give your token a definition in this list, and you're done—that's it! Reminder text like you wrote would imply such an entry exists in this list for the purpose of that custom card.111.10. Some effects instruct a player to create a predefined token. These effects use the definition below to determine the characteristics the token is created with. The effect that creates a predefined token may also modify or add to the predefined characteristics.
111.10a. A Treasure token is a colorless Treasure artifact token with "{T}, Sacrifice this artifact: Add one mana of any color."
111.10b. A Food token is a colorless Food artifact token with "{2}, {T}, Sacrifice this artifact: You gain 3 life."
111.10c. A Gold token is a colorless Gold artifact token with "Sacrifice this artifact: Add one mana of any color."
111.10d. A Walker token is a 2/2 black Zombie creature token named Walker.
111.10e. A Shard token is a colorless enchantment token with "{2}, Sacrifice this enchantment: Scry 1, then draw a card."
111.10f. A Clue token is a colorless Clue artifact token with "{2}, Sacrifice this artifact: Draw a card."
(As it turns out, the definition of Shard seems to fail to mention it uses the Shard subtype, but that seems like it might be a mistake?)111.10g. An Axe token is a colorless Equipment artifact token with equip {1} and "Equipped creature gets +2/+0" named Axe.
Great news! Thanks!
