Anything goes with the upcoming online battles for the month of May. Well, just about anything. There are going to be a limited amount of rules enforced for the recently announced Ultra No Holds Barred competition.

Trainers will be able to use any Pokémon (except for a couple of Legendary ones) in the battle. You may have duplicate party members and items. That doesn't happen much but it's all part of the rules going out the window. Participants will receive 50 Battle Points at the end of the event.

Sign-ups take place on May 17 with the actual battling starting on May 25. For a full listing of rules and guidelines check out the official website. It will also tell you which Legendary Pokémon are not allowed. Other than that, it's a free-for-all!
