I really don't think he is an idiot at all. In fact, I think he's come up with some pretty good ideas about dialga chomp. And almost everyone at my league plays dialgachomp (including dmaster) so I have had a lot of experience playing against the deck (and they play it right). Your scenario is the ideal situration, while his is the realistic situation. Now, I really don't think you have the right to be calling him an idiot just because you have different opinions. It is possible to limit your hand of trainers, but it's not easy. If you have a hand fulll of unusable supporters, and you cant put them back into the deck with SP radar because you have to grab sprays, you may well get one-shotted by gengar. It's not as easy a matchup as you seem to think, although it can be won, depending on the specific techs you run, like a third Bebe's.
