On the swampert matter, I prefer super power over pup as it gets some clean chip on ferrothorn and thats pretty much all you need to put in range of other rain abuser, mainly kingdra, as its devastating enough for teams who use ferrothorn as the only sturdy water resist.
I don't really like mega sceptile at all to be honest, it never seems to stand out because even if it possesses a stellar speed stat, it has a lot of other downsides such as having dragon pulse as strong dragon stab, leaf storm, even tho being strong itself, doesnt really break a lot of bulkier walls as it also drops your special attack forcing you to switch out. Steels are everywhere in the metagame and it cannot even 2hko things like magearna, celesteela and jirachi unless youre running max attack eq ( which is a roll to 2HKO magearna ) which is a bad set. Another issue is that it costs a mega slot, meaning you miss out on running other good megas like heracross pinsir etc. I think its only being used because its a new toy for people to test out, generally not worth it. Looking forward to other's opinions.
Well first thanks for your input on M-Swamp, I been using Super and its been very good at breaking non-chople thorn switch ins, anyway on the M-Scep, It can't ko these steel mons you mentioned but they sure ain't coming for free, neither Mag or rachi enjoy taking a quake, they aren't going down but if you're using they as your pivots then you want them as healty as possible, and while steela can take even 2 HPFire it still not a free switch in, there are things it can't get pass like AV Growth, AV Torn-T and Amonguss but it still able to put in good work against some big threats on the meta like Lando-T, Koko, Ninjas, Zyg, Chomp, Keldeo, Latios, Ttar and on.
Mind you I am not saying its the best mega ever, I think its on the same spot as M-Venu, M-Slow or even M-ZardX on while its a solid mega there still a a lot of issues stopping it from become top like the mega slot argument where M-Pinsir, M-Mawile and M-ZardY being able to tear the meta apart with few issues and the fact it has competition with serperior who is able to snowball and discouraging webs and defog with contrary, more bulk and outspeeding the 110 benchmark and slowing switch ins with glare, meanwhile M-Scep outspeed almost the entire metagame losing only to M-Zam and M-Aero and tieing with M-Bee, hitting hard form the start, having better coverage and discouragin Volt-turn Spam.
While I think M-Scep is itself the better mon, Serp its a better alternative because it doesn't take the M-slot it and do a good job as a offensive grass type, thats why its on B+ and thats why I am comparing M-Scep to M-Venu, M-Slow and to an extent ZardX who while good mons who should be taken into consideration have something who can do his job while freeing the M-slot, need a DD who can nuke the meta? Gyarados can do it, Need a bulk Grass type? Guss and Growth do very well, needing a bulky water type? Fini, Rotom-W do very good and Pex outclass it as a bulky pivot with Regenerator, recover, scald not being set-up food with haze and setting hazards.
TL;DR: M-Scep its good and can work just fine, but a serp can do just as good while not taking a slot so its like the other B megas on being good but having a no mega alternative who allows you to take another mega.
Changing topics a little what you guys think about the upcoming megas ? M-Ttar I think it on the same spot as M-Gya as his base form has more utility than his mega so I don't think its gonna show too much, M-Aboma its pretty mediocre being very slow and having a bad type on Grass/Ice it can work on hail teams but other than those its not that great, M-Mane might end up being very good or average, Its a good partner for koko since it can hit stuff like AV-Growth and Guss, having Intimidate weakeens stuff for his teamates and on E-Field his stab packs a punch, M-Gallade still has to compete with M-Cham but the better speed might give him a niche, M-Garde has to compete with Lele but together they seem very good being able to weaken his checks and both having very powerfull stabs and M-Lop not having to pick fake-out to go fast from the get go is very good, while a good move to rack in damage it frees a slot for something like POP or Sub who are good as well.
