I managed to get my entire Sandstorm team to level one hundred, minus my Skarmory, who is well on its way, at level 67. At my friend's house a few nights ago, I took my team into a semi-large Pokemon tournament he had set up on Pokemon XD. Personally, it wasn't that hard (they don't even know what EV training is), so eventually we set up a double battle, and I tested my sandstorm team's double battling ability. I had to use my own two games, as I fought two other people, except my other team isn't really a sandstorm team. Note: I used no ubers, they used.. like what? Five?
I was really surprised. My sucky not-so-good LeafGreen team managed to keep more Pokemon alive than my sandstorm team. I think they were worried about my Sandstorm team more, though. I especially like my finishing attack; my two Swamperts took out a Mewtwo and Ho-oh with an Earthquake-and-Surf combo. It was considerably more challenging, but I managed a win. The great thing is that it was all recorded on a dvd!
