Sorry for late reply, I was away this weekend.
Have you got them all yet? I don't know if I should cheat for the cake or just wait. The Tiara will take a while to get, I'll have to find someone, awkward xD
What about the Battle Subway, are you trying for that Trainer Card upgrade? I'm failing. I can't even get past Normal lines (Multi and Single, I've done Double :D). I want to use my in-game team to beat the Normal lines then I can breed/ev/whatever a team to beat the Super lines.
