Im gonna have to disagree with this, rain is not the same thing it was when Mega Pert was released, toxapex, kart, ferro and stuff like dat got a super surge in usage and some of them even a new ranking, i dont see rain going up anytime soon, tbh of anything it shud go down.These two:(currently B+)
I can kinda see why you wouldn't rank them with stuff like M-medi, M-maw and M-pinsir in A-, but I also think they're definitely better than most other things in B+ like M-zam, Blace (lol), Latios, Venusaur, ... Seeing how A- also has Chansey, Gliscor, regular Gren and Magnezone I can actually see the faces of Rain fit in there quite nicely.
The playstyle has been consistently good ever since M-pert got released and never really slowed down. It's performed well in a couple of matches in SPL and even though everyone knows what they do by now, you still can't afford to build a team that isn't prepared for them because you will absolutely lose more often than you'd like.
As for meta trends:This thing getting Defog is pretty frickin nice. I already ran Rain with Flynium-Z Torn in SuMo, but you're pretty much obligated to slap Defog on Pelipper in that case, which reduces its durability over the course of a match, or put it on Koko which sucks even harder. Well, not any more! This bird has been praised enough over the last couple of pages, but I'd just like to mention that it's yet another option you have now when building rain besides A-Gren (specs or Waterium), KokoLucha, Kingdra, ...
I'm interested in your thoughts on this. I could see why you might not want to raise them, but I feel like B+ is underselling one of the playstyles that definitely is one of the more important ones in OU. (For reference: M-sab is also B+, and Stall imo is way less potent than Rain)
I could post some SPL games, but I think everybody pretty much knows how Rain works by now.
