First of all you can only pick two of the same character in the arcade. You can never pick three of the same character because it is useless. If you take the time to read my thread you will see that your guys’ posts are rediculous.
This is for the one that said you won’t get disqualified if you mess up the cloning: The arcade in tournament setting will reset itself after every match (kind of like VS mode in the home versions) so you would have to pick your characters all over again regardless of whether or not you win or lose.
For the guy that said you can pick 3 Akumas, etc: It is impossible to pick three of the same characters as stated above. You cannot pick the bosses in the arcade, just normal the normal versions of Iori, Akuma, Ryu, and Rugal.
For everyone that said picking two Sagats, etc: As I stated a few posts up this one: You can clone anyone in the game except for top tier characters like Bison, Vega, Sakura, Blanka, Sagat, Cammy, etc.
And last bu not least: No one cares if you pick two Dhalsims or two Dans, etc.
