Not necessarily, since 'best team' would largely be based on someone's personal opinion, and 'current conflict' could be mistaken for the SM rules of the day that the contest post came out.
Rather, for the strategy contest, all contestants have to do is ensure that the team they make meets the SM gameplay requirements, on the day that their entry is posted - I make a note of the mana cap & its associated rules when they change, so I'll be able to tell if an entry is valid or not. :)
