Banned stage

Banned stages are stages that are banned from most official tournaments. These stages can be banned for several reasons, including:
 * Providing an unfair advantage for a certain character
 * Allowing players to abuse glitches in the game
 * Completely re-vamping the strategies needed to win (such as Temple and Icicle Mountain)
