Dave's Stupid Rule is a regulation that is in effect at most tournaments. While there are minor variations of the rule, they all have the same intention: to prevent a player from having an unfair advantage by playing the same stage multiple times in a match. The rule is named after the smasher Scamp. Another variation says that if the player counterpicking chooses random for the stage, a stage may be played twice. In some tournaments, where only three or four stages are allowed, this is often a viable strategy to get the same stage twice in one match.
