I'll start this so RB finally gets its own prefix :P So, let's discuss what strategies we're currently using on our teams, so that we have a better picture of what's current meta. I personally run weather (specifically, Hail) abuse, with a dash of Sashed Pokemon. It's classic and effective. Abomasnow always leads unless I see something like a Politoed. Anyone else?
I tend to run dual weather, (TTar + Toed) and choose which I use, - if any depending on the opponents team, Toed is a nice answer to something like Mamo, whilst TTar does well vs Latios. I also run 2 sashed priority users, then 2 strong attackers, one of which being a sand abuser.
I have 4 scarfers. Scarf Glaceon catches peeps by surprise, doing hefty damage to most dragons (barring lati@s with its massive sp. def stat) and shadow ball, signal beam, and hidden power. Balloon Metagross, with explosion/earthquake/bullet punch/some other move I forgot right now, which acts as the team's priority user when I feel I may need it, and an excadrill counter too. Scarfed Zapdos, with heat wave/thunderbolt/extrasensory/sleep talk, acting as sleep absorber, and has decent coverage. Scarfed darmanitan with flare blitz/U-turn/earthquake/superpower hits way hard and fast. Dies quick, but often brings down a lot with it - its flare blitz, even resisted, is damn powerful. Scarfed jellicent adds occasional useful coverage with shadow ball/energy ball/surf/water spout or something like that.. then some other 6th pokemon is there to abuse rare trick room teams, which otherwise cause this team hell.
