One of the most challenging Pokémon GO competitions, the Master League Premier Classic, will be live starting from Sept. 29 to Oct. 6. These battles will not be a walk in the park, so stock up on revives and take a look at some of the best team suggestions to be victorious.

What Are the Rules for the ML Premier Classic?

There are a few things to keep in mind before jumping into the battle. Trainers will not be allowed to use a Pokémon that was given a Candy XL. Mythical and Legendary Pokémon are also prohibited from the competition. Luckily there will be no CP limit for entry, so be sure to use your strongest Pokémon. Just make sure they are not past Level 40.
