Couldn't really do anything against Thundurus game 1, won game 2 clean and lost to a para and a miss on game 3 (I did Psychic the turn Diggersby came in). Can't say those were good games, abut it's not like anybody controls luck in Pokémon and, please, don't feel bad for it. It's not your fault at all.
I wish I could play and go far but you can't get anywhere in this game without a bit of luck, and I agree with that whenever I play a Pokémon match.
ggs and gl in future rounds.
