Tournament legal

Tournament legal refers to stages, actions, and sometimes even characters that are allowed to be used in tournaments. Each game has different standards for what is tournament legal due to a wide variety of stages as well as that characters and game physics are changed every game.

Stages
The most Tournament legal attention often goes to stages, in order to determine which stages are suitable for tournament play or not. Stages are placed into one of three categories, and though rare can change categories.
 * Starter, a stage that is generally recognized as fair to most characters and can be picked any time.
 * Counterpick, a starter stage which, while legal, gives advantages to certain characters. These stages are often chosen by the player who lost in the last round.
 * Banned, stages that are not allowed in tournament play due to giving certain characters an unfair advantage, or whose layout is random, has severe hazards, or allows for camping or stalling. A majority of stages in the Super Smash Bros. games are banned.
