It's returning an array of action cards the players have played, but I suppose I could've totally just done chosen_actions.values() now that I'm looking it over, it's totally due for a bit of a refactor I just never stopped to think about it lol
Oh wait! It's doing more than that, it returns all actions in the players hands. This was meant for an action effect that I never actually added. In theory a card could do something extra if a tie triggers while it's in your hand. I do have cards that have a bonus when playing during ties but that's a different mechanism. I think I was planning on the growth ability to be a tie only thing but that made it way too slow, and tbh even per turn felt too slow which is why unlockable characters growth cards grow way faster.
