Shatter the Oath

In 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.

Hexproof 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.

Some 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.
