45 – Rules of Red Skull reads: when a side scheme is defeated, goes to the discard pile of side schemes…

In the Red Skull scenario, only shuffle side schemes from the encounter deck into the side scheme deck; do not shuffle any player side schemes into that deck. After defeating a player side scheme during that scenario, place it in its owner’s discard pile. Any side scheme (player or encounter) with the Victory keyword should be placed into the victory display when defeated instead of in a discard pile.
