Dave's Stupid Rule

Dave's Stupid Rule is a regulation that is in effect at most tournaments. It is quite simple, stating that no stage that has already been played in a round may be picked for another game in the same round. For example, a random pick choses Final Destination for the first game of a Falco v. Ike match. The Falco player loses, so s/he gets to pick the next stage. S/he want's Final Destination again, because it is a good Falco stage. However, Dave's Stupid Rule states that Final Destination cannot be played again in that round, so the Falco player must pick a new stage. The rule is named after the smasher Scamp.
