I think that Metagross-Mega should get moved up to A-, or at least B+. It's honestly just that useful. First and foremost, it checks Xerneas really well. I honestly think it's one of the top 5 Xerneas checks easily, if not even higher. Secondly, it can revenge kill lots of stuff with Bullet Punch. You might think Bullet Punch is really weak, but it can be really useful for revenge killing, a little bit like Extreme Speed from Arceus. If you use max attack (which I do) you can do over half most of the time to uninvested Mega Gengar, and always do over 40% to standard Darkrai. If Xerneas gets away from you (and Metagross is low on health) it can pick off Xerneas from 50%, and sometimes as much as 60%. Not a game changer, but it has a lot of uses. It's better than Scizor's Bullet Punch in XY, and that made Scizor a pretty big part of the metagame. Another great thing is the speed tier- 110 outspeeds Primals, Rayquaza, etc. You can run max speed to speed tie the Lati twins, but you usually wall them anyways, so there is no huge point to it. Outspeeding any Groudon is the priority to me, as well as Kyogre (if you have grass knot.) By the way, Earthquake is usually enough to 2HKO Groudon. Super defensive ones might live, but they will take an irreversible hit, and might fall if hazards are up. There are cons in that it is kind of Dakrai and Arceus-Dark bait and has a lot of annoying issues with Earthquake, but the mon is still worth using. It's one of the best mega evolutions around, and one of the primary ones to consider along with Diancie, Mence, Gengar, and M2Y. Flaws are there, but I do think it is worth using and the power and bulk and typing outweigh the flaws as far as I am concerned. Thanks for reading.
