Here are my thoughts on all the mons
aim brought up:
This thing, while it has a niche, it is a very good niche. VoltTurn is a really good team archetype at the moment and Mega Beedrill does this job best. Yes, it may be outclassed Mega-wise as Mega Aerodactyl is a faster Mega, but Beedrill has a STAB Adaptability-boosted U-turn which can hit even resists hard. While this thing has a rocks weakness and is very frail, it is able to get out of any unfavorable situation thanks to U-turn. However, while it has all this going for it, the metagame has also prepared for it with things like Bulky Itemless Crobat, Mega Aggron, and Tentacruel. Move to
A- imo.
While I have never had experience with its Toxic Spikes set, I can attest to this thing's power. I was using this as a wallbreaker awhile back with Choice Specs and even resists are hit super hard by its Adaptability boosted STAB Draco Meteor. This thing's great typing is not only cool offensively but also defensively, resisting Heracross's STABs and Fighting spam in general while also 4x resisting Grass and resisting VoltTurn. I agree with moving this up to
A-.
Meloetta is a great Pokemon that is very versatile, with sets ranging from SubCM to SpD to help stall beat out usual stallbreaker mons such as Reuniclus and Heracross. This versatility also means it has different checks and counters, meaning it can last well throughout the match. I feel this at least needs to move up to
B as this more is very valuable to stall thanks to its access to Perish Song and it is a really good win-con thanks to its amazing bulk and decent Speed stat.
This panda is a cool mon as it has the awesome typing on Scrafty, but without all the rightfully deserved negative connotation, lol. While Heracross outclasses it as an overall physical attacker since Heracross has Guts to check status and Moxie to sweep, Pangoro has access to decent coverage options alongside decent STABs. Gunk Shot is a particularly good option as it allows it to get around the Fairies it should be scared of. I say
B+ for this panda.
Ah this guy. Such a weird Pokemon, yet a really good one imo. The fact that it checks so many prominent threats such as Entei, Mienshao, and Heracross due to Intimidate and decent typing along with access to things like Destiny Bond, Toxic Spikes and Spikes, Thunder Wave and Taunt makes it a great utility mon that fits better than Tentacruel (although arguably Tentacruel is the best spinner atm so you have to go for spin support or utility support). I agree with moving this up to
B.
This bulldog is one of my favorite Dragon checks. I also love how I made a very successful team with it. Besides that, the fact this can check non-Iron Tail Salamence alongside threatening it with a STAB Play Rough or crippling it with a Thunder Wave means it can check one of the top tier threats. Intimidate also really helps its bulk, allowing to threaten more Pokemon than it could with its otherwise average 90 / 75 / 60 bulk. With my bias, I would love to see this at B, but being reasonable I feel like
B- is fine for this doggy.
