I'll allow one suit per battle the most there's ever been were remote controlled plastic soldiers. The trial system is not allowed because just simply shutting down enemy suits is BS. Armor has no place in this universe. A infinite justice gundam got blown out of the air by a physical based zaku amazing. There is no difference between what suits can and cannot do outside of quality, the age of which they were made in (custom suits tend to have an advantage over normal suits) and how well the pilots can fight. There can be up to two pilots fighting in the same suit at once. One as a tech the other controlling a suit but most people only fight by themselves. Reiji and Sei fight as a team but Ricardo Fellini fights by himself and is still a freaking beast. As for teams we're all going to be on the same team so numbers will be decided on when people join. If two people really want a fight they can do so in a practice arena outside of the tournament.
