Pokémon Duel has officially begun its first Team Battle. This in-game event has you and other players selecting a team, opening up Time Boosters and winning battles in order to earn points. The team with the most points will win a Rare Metal EX while reaching certain point levels for your wins. You can also increase your points and Team Powers – a point multiplier – by using Booster Enhancers. The lowest ranked Team will get extra Team Power.
