What is the best way to get the N card? I have gotten so many R's and the SR, but the N just won't show no matter what I do. I have thrown so many R-Gacha tickets, candies, perocolo tickets, and everything else at her and just get the gold 1/3 upgrades and N gacha tickets. And running out of time, because it is changing on the 30th. I would think the N would not be the hardest to get.
