There are 2 modes on cart, Normal rules and No restrictions. Normal rules is level 50, no candies. No restriction is any level and any amount of candies. Theoretically there could also be a Normal rules AG on showdown which allowed multiple Mewtwo since thats how the Normal rules is on cart. It just also they'd be forced to be on level 50 and have no candies. But they decided to use the Normal rules format for where they'd put the smogon clauses, not create a Normal rules AG which would mimic the cart rules, and also used the No restrictions format to create AG and doubles AG.I prefer the candies meta with actual clauses, so its not just who hits the horn drill first and 3 mewtwo on every team. It would be nice if we had sleep clause, species clause, OHKO moves clause, and evasion clause as all of those things just break the meta. Its weird that this is the "battle spot" version at level 100, while the "ou" version is level 50.
