If you’re as Pokémon TCG Pocket -pilled as I am, you’re desperate for new cards to collect and new events to battle through. Fortunately, it sounds like players won’t have to wait too much longer for either one, at least according to the latest datamined leaks coming out of the mobile card game.

An upcoming Pokemon TCG Pocket PvP event will feature one the toughest challenges we’ve ever seen in the game, and players should be worried.

While everyone is saving up their pack points in the hopes of finally getting Mewtwo EX or Gardevoir to complete their decks, the cards they really need might already be in their collections. Rare cards aren’t the only strong ones in Pokémon TCG Pocket and you can build something strong mostly using common cards.

Opening up card packs is the progenitor of loot boxes, so we can all recognize that occasionally icky feeling while playing Pokémon TCG Pocket. Keeping track of all the game’s numerous currencies certainly doesn’t help in that regard either.
