I kinda like what we've gotten this time around, Mega-Swampert leaving is probably more of a game changer then any of the new drops and I'm prefectly fine with that, not everything needs to make a big splash in the meta to be effective. As for my thoughts on each of them, well.



M-Banette has only gotten worse this gen thanks to the prankster nerf, and to add insult to injury dark types are a common sight in UU. I can't see it being used outside of metronome battles and low ladder.



M-Aggron will definitely see some usage thanks to it's massive bulk and handy ability, but as long as Xurkitree is here I think M-Steelix will be generally favored over Aggron. It's also worth pointing out that M-Aggron doesn't handle Z-Thunder Lati terribly well either, so another point for Lix.

+1 252 SpA Latias Gigavolt Havoc (185 BP) vs. 252 HP / 240 SpD Aggron-Mega: 248-292 (72 - 84.8%) -- guaranteed 2HKO



Scolipede and Salamence are both in the same boat of being BL mons who we're pretty sure are still a bit too much for UU but might be worth testing at some point in the future, their Z-move sets make them pretty dangerous so their chances of seeing action seem iffy at best.



M-Abomasnow will be interesting to see in action and could possibly shake things up quite a bit, adding an extra nail in the coffin for any remaining rain teams while also giving us something else to toss at Xurkitree in hopes that it'll be able to check the opponents set. It's typing and speed will probably hold it back from being a major threat but it's something you'll want to keep in mind.



Manaphy doesn't really need to be discussed, does it? I can't see this thing staying and I doubt anyone would be able to make a good argument in favor of keeping it.



M-Camerupt has excellent timing, joining just as rain teams take a heavy blow, it might be fairly decent in the current meta with things like MowTom and Weavile running around, but I can't see it working terribly well outside of Trick Room. It still falls over to Xurki's Grass Knot too.



TL;DR version: Rain is a lot less scary and we have a few new options for team building
