Now that the ladder is reset, I don't see the point on laddering with the RW pokes. So, I'll just post when I first got past the 1250 mark
I used a Chesto/Rest set and overall I ended up using Volc as fodder most of times. Even when I had the sun up, Giras would just wall me. Only cool thing was to tie with scarf Palkia or the random burns on Ray/Arceus when trying to revenge. There is no way to effectively use it. Max speed is necessary, priority just rapes it, if you go with bulky set, then it doesn't do much damage until you hit to +3.
