Classic Mode Ticket
Classic Mode tickets first appeared in Super Smash Bros. Ultimate, they can be used to prevent using coins to continue and prevent the intensity going down after failing a round. As with any continue, after using a Classic Mode Ticket, the difficulty will no longer be able to increase to 9.9, but if the intensity is already there, they will not have an effect. They can also be used before selecting the intensity and starting a Classic Mode game to increase the rewards given out when finishing the mode.
