If the Legendary Tourney thing comes into play, probably best to wait until D/P come out and give a few more pokemon?
I don't know much at all about D/P pokemon since I'm trying to keep the experience "new", but surely there are a few legendaries that would be elegible. The more the merrier.
And I certainly like the idea of the Legendary Tourney. Gives you a chance to use some pokemon that you'd literally never get to use otherwise.
Good to hear about the D/P attacks. Sounds like everything might be ready by the time D/P come out, which would be a nice change from the Ru/Sa transition. I remember R/S being out for almost a year before I left ASB for a while, and RS pokemon and attacks were still disallowed in ASB.
