She's a free 6☆ card that has nothing to do with ranking. Even though her stats are near the low range, she still has similar stats to some premium 6☆ cards. Having a huge restriction/luck based seems logical on a game that's giving away a premium 6☆ card.

Giving everyone free 6☆+2 cards based only on hard work seems like a terrible idea and would only result in power creep (Both you and I played a game that resulted in this). I missed out on her too due to my bad luck. Ranking is different because well, you kind of have to do a bit more than hard work to rank, like spend money or trade cards for pots.
