10 rulings from Wizards of the Coast
- 1 September 2023If two or more Roles controlled by the same player become attached to a permanent at the same time (perhaps due to an effect such as that of Doubling Season), that player chooses which one to keep and which are put into their owners' graveyards.
- 1 September 2023If a permanent has more than one Role attached to it controlled by the same player, each of those Roles except the one with the most recent timestamp is put into its owner's graveyard. This is a state-based action.
- 1 September 2023Cards in the Wilds of Eldraine main set create six different Role tokens: Cursed, Monster, Royal, Sorcerer, Wicked, and Young Hero. A seventh Role token, Virtuous, is created by Ellivere of the Wild Court, the commander of the "Virtue and Valor" Commander Deck.
- 1 September 2023Hexproof and shroud won't prevent a Role from becoming attached to a permanent if the ability creating that Role attached to that permanent doesn't target it.
- 1 September 2023If Faunsbane Troll is no longer on the battlefield or no longer a creature when its activated ability resolves, it doesn't fight the target creature, but the effect that causes the target creature to be exiled any time it would die that turn still applies.
- 1 September 2023Some spells and abilities that create Role tokens require targets. If each target chosen is an illegal target as that spell or ability tries to resolve, it won't resolve. The Role token won't be created.
- 1 September 2023Roles are colorless enchantment tokens. Each one has the Aura and Role subtypes and the enchant creature ability.
- 1 September 2023A permanent can have multiple Roles attached to it if each one is controlled by a different player.
- 1 September 2023If Faunsbane Troll's activated ability resolves, its effect causes the creature to be exiled any time it would die that turn, not just if it would die as a result of damage dealt by Faunsbane Troll.
- 1 September 2023In rare cases, a spell or ability might attempt to create a Role token enchanting a permanent that it can't legally enchant (because of an ability like protection from enchantments). In such cases, the Role token isn't created.
