cr:6.3.6
Continuous effects that remove a property, or part of a property, from an object do not remove properties, or parts of properties, that were added by another effect.
Example: Erase Face has the text “When this hits a hero, cards they own lose all class and talent types until the end of their next turn,” which removes any existing class and talent supertypes of the object, but does not remove or prevent the addition of class and talent supertypes gained from other effects, such as Brand with Cinderclaw.
