Far as I know, restrictions are 60 card (max) decks. As for the other restrictions, might be worth some digging into see what the last set of restrictions they put on the game was. I vaguely remember the no more than four of any card rule. I think that was envisioned as a way to limit vehicle decks. Do we want to revive the old banned list? i.e. Dasher D's, Nightsky's, Improved Dmg, etc.?
