late as shit to this thread but for someone with 5794 battle points in pearl i'm obviously very excited for the battle castle. it's a great concept for those who feel that they should earn something to directly benefit their battle frontier progress by winning many battles in a row, not just the battle points that earn you stuff that is useful in your general ingame and wifi exploits. i suppose this concept started with emerald's battle factory but it is pretty shitty to have to break the synergy of what's probably a good team in order to get better IVs for your pokemon, and i hope they've changed that in platinum but i really doubt it
