I can't remember what we said if this was to happen so I'll ask
@Reo again lol.
However, tbh if someone enters one of the "rare" cards directly, that same Rare card can still be included by Cards Team as it is part of the current Rare list of cards for that batch. So I would say that yes, if Hara is indeed part of the rare list for 3rd batch and she is entered by a participant, then Cards Team will still include Hara (thus 2 being in the Roulette). This doesn't break the rule of "no duplicates" as it's Cards Team entering the 2nd card, not a participant.
