By the wording of Arcane Curse, it seems like if it were the only card left in your hand at the end of the round, it should discard itself. It doesn't. If this is the desired behavior, the card could be reworded to "...discard your oldest card other than this." Code: BATTLE LOG: Scenario=Garnet Portal Bones,Room=GADP (Dash),RoomID=240582,Msg=Starting round 2 BATTLE LOG: Scenario=Garnet Portal Bones,Room=GADP (Dash),RoomID=240582,Event=Attachment Phase Initiated BATTLE LOG: Player=Dash,Scenario=Garnet Portal Bones,Room=GADP (Dash),RoomID=240582,Event=TriggerSucceed,Trigger=Arcane Curse,TriggeringActor=[Null],AffectedActors=,TriggerType=StartTurn,TriggerLocation=Hand BATTLE LOG: Player=Dash,Scenario=Garnet Portal Bones,Room=GADP (Dash),RoomID=240582,Group=Radagast,Event=Nothing to discard
