cr:2.13.4
If an effect refers to a group of cards by a trait, it refers to all cards with that trait.
Example: Arakni, Web of Deceit has the text “At the beginning of your end phase, if an opponent is marked, you become a random Agent of Chaos.” This refers to a group which includes all cards with the Agent of Choas trait, and selecting one at random from that group.
