There are a total of 376 different custom moves, most of which are awarded randomly. To get them quickly, you can try to get the red wrench icon during the roulette wheel sequence in Classic mode. Press Home to pause the game while the roulette spins. If the wrench icon is just above the icon that is selected while you paused, hold A and resume the game. The wrench icon should roll down and be selected. If the icon selected was the wrench itself or if the wrench icon is not above the one that is selected, do not press A and resume. Instead, repeat until the wrench icon is above the icon that is selected. Note: If you allow the roulette to roll for too long, it will eventually come to a stop automatically. With some patience and constant grinding, you should be able to unlock all the custom moves for your desired character quicker than normal.
