Personally, I think that Palkia and Dialga should be pushed a rank back, and Zekrom and Giratina should be pushed forward. Especially Palkia. I watched that thing take THREE Judgements and live, then murk Arceus in ONE SHOT. Also, I think you should add RCs to the shop, or maybe even some eggs. As achievements, I think beating a Gym Leader without losing a single team member, or Defending your badge in a shut-out should be achievements.
Also, PKM, I challenge you for your badge.
