I also now use Yamask, Bold nature and evolite, and it's evolution...Plus I use Scrafty, Gigalith, and Carracosta as walls and potenial sweepers
Funny, I never thought of using a team like that, but this random wifi battle things hard, since it 3 on 3, you can never tell what pokemon your opponents gonna use, at leat with 6 on 6 you know the pokemon they have will be played at sometime
