Pokemon: Sword and Shield may have introduced the frankly grotesque Eternamax Eternatus, but back in my day the strongest Pokemon was always Mewtwo. Whether you were playing the games, trading the cards, or – as I did – quite literally pretending to be Pokemon with your friends, Mewtwo's place was well-established as the greatest of all time.
Such is the case in Pokemon TCG Pocket, where all of sudden, every opponent you face in 1v1 seems to have the same identical deck: two Mewtwo EXes, two Gardevoirs, and maybe a Chansey that they barely touch. This combination is proving almost impossible to beat, with twin Gardevoirs piling two free psychic energies per turn into Mewtwo EX, whose Psydrive attack for 150 HP (which ordinarily discards two energies per use, so takes some time to build back up) can then be used every single turn.
