"Not necessarily - while it would hurt (in a single match vacuum), in a large-scale tournament, you have to prepare for other teams, and not just counter one. I signed up for a tag-team WiFi tournament as a VGC player and had to face batpig's brother - he completely demolished my '09 team, no doubt because he knew what my leads were. If that were the VGC, he couldn't do that (in theory), because countering a Follow Me/Dark Void combo means you won't necessarily be able to handle a different team (like Trick Room)"
Are you saying batpig's brother scouted your team and made a team especially for you?
