Team databases for semirandom battles

[gbagcn]

I came up with this idea because I like using a variety of teams but I hate creating them. To start out a massive database to teams (100+ teams) would have to be created ideally by multiple people since it would be too much work for one person. There should be some consensus within the community that these are good teams. Each team would be given a number (1-100+). Before the battle both players would use a random number generator to select which team they would use. They would then battle normally. Would anyone be interested in this idea or is this a bad idea for some obvious reason?
