Nerf Giratina EX & Balance issues
Simple as that. Giratina EX is meta centralizing and is bad for competitive balance. It shouldn't be allowed to get an energy first turn. It is simply press "A" to win type of play and effectively prohibits any other type of decks without a counter to it. The issue is that Giratina EX shouldn't allow the first turn player to receive an energy. It's EX move should be more punishing in terms of recoil damage. Also, the lack of strong EX counters means your deck has to have a Giratina Ex or face losing immediately when you have tbe opponent spam Sylveon EX.
Too many EX Pokemon are just absolutely worthless and only about 10% of the current card list actually have tournament viability.
Pocket TCG should also add resistances which would help with competitive balance.
Also, pocket tcg, wtf is up with some of the absolute ass cards you make? Tropius at 110 hp with a 3 energy 60 DMG move. This is absolutely garbage. Don't make throw away cards that have zero viability. All cards should have a purpose even if their use is a niche one.
Pidgeot EX is the worst EX card in the game.
