Wow, did RU ever take a blow. While I haven't played the teir before personally I've read enough to know this is going to completely reshape the tier once again. I feel bad for all the people who have to rework their teams now.
As for OU, I honestly was really expecting Scrafty to drop and Deoxys-D to rise, but it looks like we're going to have to wait another 3 months at least before Scrafty makes the fall. Deoxys-D being banned from UU isn't much of a surprise to me either, as I've been hearing so much complaining about spike stacking in the teir and even in OU nothing can really stop Deoxys-D from getting up its spikes.
