I'm so tired of seeing garbage teams on ladder. To illustrate my point, I used a team of only a Smeargle and a Shedinja. It tears apart unprepared teams, and it should be very easy to prepare against (even if you're not thinking of that threat). I chose RU because it was the lowest tier Smeargle was in. I understand this is low ladder, but you can't be that bad to lose to two 'mons.
