Why is excadrill banned btw? I don't play pokemon online (although i do want to get round to it) and i know that legendaries are banned, so why excadrill?
Legendaries aren't banned. Pokemon that prove too powerful for use in standard play are banned. Whereas an overwhelming powerhouse such as Mewtwo is legendary and is banned, so is Wobuffet. Not to mention many legends that are in lower tiers such as Entei (because Entei sucks balls).
Excadrill was banned after a round of suspect testing. Community leaders eventually voted that it was too powerful (mostly in part to it's immense speed and power in sand) to be allowed in standard play. Other notable bans of this generation include the banning of the use of the abilities Swift Swim and Drizzle in the same team, as well as the banning of Blaziken (due mostly to its acquirement of the overwhelmingly powerful ability Speed Boost).
