I want to comment on Yanmega, but I'm finding it strangely difficult to gather my thoughts on either end of the argument. Overall, Yanmega is terrifying to see in the opposing preview. More so than Hitmonlee or Moltres or almost anything bar maybe Exploud. I've never had too much trouble with the speed boost set bar air slash hax (which happens far too often), but Tinted Lens Specs is undoubtedly one of the best wallbreakers in the tier. Theoretically, offensively-inclined teams should be more afraid of the LO Speed Boost set, and it perhaps is more threatening, but I find it much easier to play around given the reduced power. Some careful switching and decent preparation are generally enough to quell the bug. Furthermore, mons like Fletchinder and Magneton really put a damper on LO's sweeping abilities. This is not a problem for specs, though. If you are using an offensive team, something will die whenever it comes in. If you are using a defensive team, if you aren't using registeel or spdef aromatisse, or one of them is worn down just a bit, Yanmega can exert ridiculous amounts of pressure, relatively easily paving the way for another mon's sweep. The opponent generally has something to force it out after the fact, but that does not alleviate the damage that Yanmega had already done. With hazard removal support from the likes of Hitmonlee, Gligar,
Avest Trick Lopunny, etc., there is nothing preventing it from repeatedly coming back in and wreaking havoc. Perfect prediction aside, it can be checked by mons like Rhyperior and Moltres, but a smart Giga Drain or Air Slash (or even HP Rock) could spell doom for these mons (who both have much more to focus on than just walling Yanmega).
As Molk mentioned, Sticky Web is very helpful to Yanmega, namely the specs set, as it turns it from a wallbreaker to nearly a sweeper, as it is now much more difficult to force out after the kill since it will now be faster than almost all grounded mons. At this point in time, I definitely support
Yanmega to A+. Perhaps this will be less true after a bit of metagame development. The possible loss of Sticky Web, a rise in mons like Magneton and Fletchinder, faster teams, etc. could all hamper Yanmega's performance. Until then though, it is a rough mon to handle.
While on the topic of dangerous Bug-Flying types, I would like to nominate an unranked mon for somewhere in the
B Ranks: Scyther. Scyther has been quite overlooked this generation, but its deceptively great bulk, blazing speed, offensive synergy with common mons, and flexibility make it a definite underdog. To expedite this post, I'll break it up into a couple of Scyther sets, analysis style:
Scyther @ Eviolite
Ability: Technician
EVs: 216 HP / 252 Spd / 40 Atk
Jolly Nature
- Swords Dance
- Aerial Ace
- Baton Pass / Brick Break
- Roost
This is the set that I find most suited to the current RU meta, and the one that I have been using the most. Scyther has an incredible amount of setup opportunities with this set. It can realistically setup on more than half of the S/A ranks 1v1. If the opponent is coming on on a switch/on the revenge, it can tank an even more impressive quantity.
252 SpA
Delphox Fire Blast vs. 216 HP / 4 SpD Eviolite Scyther: 264-312 (78.8 - 93.1%) -- guaranteed 2HKO
252 SpA
Moltres Fire Blast vs. 216 HP / 4 SpD Eviolite Scyther: 282-332 (84.1 - 99.1%) -- guaranteed 2HKO
252+ SpA Life Orb
Yanmega Air Slash vs. 216 HP / 4 SpD Eviolite Scyther: 260-307 (77.6 - 91.6%) -- guaranteed 2HKO
252 SpA Life Orb
Jolteon Thunderbolt vs. 216 HP / 4 SpD Eviolite Scyther: 273-322 (81.4 - 96.1%) -- guaranteed 2HKO
And let's keep in mind that these are some of the strongest common STAB Supereffective attacks in RU. In terms of general tankiness:
252+ SpA Life Orb
Reuniclus Psyshock vs. 216 HP / 0 Def Eviolite Scyther: 146-173 (43.5 - 51.6%) -- 9.4% chance to 2HKO
252+ Atk Life Orb
Sharpedo Crunch vs. 216 HP / 0 Def Eviolite Scyther: 142-169 (42.3 - 50.4%) -- 1.6% chance to 2HKO
252 SpA Life Orb
Zoroark Flamethrower vs. 216 HP / 4 SpD Eviolite Scyther: 192-229 (57.3 - 68.3%) -- guaranteed 2HKO
252 Atk Life Orb Hustle
Durant Iron Head vs. 216 HP / 0 Def Eviolite Scyther: 181-214 (54 - 63.8%) -- guaranteed 2HKO
252+ SpA Choice Specs
Exploud Boomburst vs. 216 HP / 4 SpD Eviolite Scyther: 237-279 (70.7 - 83.2%) -- guaranteed 2HKO
This, backed by STAB Technician Aerial Ace off of a likely +2 attack makes Scyther very threatening to common mons. Perhaps the most interesting part of this set is the third moveslot with Baton Pass / Brick Break. Scyther can choose Brick Break to take on a more traditional bulky sweeping role. It allows it to better handle Registeel, Electric Types, and Rhyperior (good luck with most of those). The almost universally greater option is to forego this coverage in favor of
Baton Pass. With this move, Scyther's utility goes through the roof. It can not only support its teammates with a +2 attack pass, it also increases its sweeping potential exponentially by allowing it to essentially tap out when faced with something that resists flying/can threaten a 2hko. This is where those previous calcs come into play. If something like Jolteon comes in to revenge Scyther, it can tank a hit if it is healthy and pass to another mon who can continue the sweep, likely with a free turn. This process is even more dangerous when Scyther is faced with a mon that it can outspeed (ie. almost the entire tier). It can pass out of something like Moltres into, say, Sharpedo or Rhyperior. The opponent must now sack either Moltres, likely one of their few Scyther checks, or probably get nearly swept. If the former occurs, than Scyther is still healthy and ready to repeat. In the event that Scyther is slower than the opposing threat, Scyther itself will be crippled, but a gain is made in that the pass recipient will come in unscathed and ready to sweep.
As evidenced by the popularity of Vivillion as a point of interest, mono-flying coverage is pretty great in RU. Frequently, Scyther will be able to do quite a bit of work on its own simply with a boosted Aerial Ace.
Scyther @ Life Orb
Ability: Technician
EVs: 252 Atk / 252 Spd / 4 Def
Jolly Nature
- U-turn / Swords Dance
- Knock Off / Brick Break
- Aerial Ace
- Quick Attack / Brick Break
It can also take a more active role as an offensive pivot. This set takes greater advantage of that beautiful base 105 speed by using Scyther as a nightmare to many offensive teams, Sticky Web included. This set is more self-explanatory than the first, so I will keep things brief, but Scyther threatens generally the same things as before, except it has a far greater emphasis on individualized sweeping. It is perhaps more threatening to Sticky Web Offense than the first set, but it doesn't fare as well as the bulky varients in the typical metagame.
Scyther also has a number of other cool options. It does have access to defog, though it does not mesh well with its SR weakness. It could possibly run a full-on defensive set with its fighting resistance, high speed, and natural bulk doing wonders for stallish teams. Even Endure-Reversal is a possibility. The fact that it is unaffected by Sticky Webs, in a similar vein to Yanmega, makes it incredibly valuable in the current meta. Pairing it up with mons like Cobalion can allow for either a cool volt-turn core, or a devestating SD-Pass core, as Cobalion can easily tank any of the physical attacks, particularly rock moves, that are being used against a weakened Scyther.
I know that
Kiyo use Scyther quite a bit during the Lass test (and it was quite scary every time I faced him!), so perhaps he could expand a bit?
Overall, I think that
Scyther to Bish Rank is not much of a stretch at all. It is significantly better than mons like Pangoro and Eelektross, and its viability is only further increased by its easily identifiable niche that something like Pangoro just doesn't have.
Side note:
Cincinno for B- or C+. It found a niche in killing the shit out of Frosslass. That's over, and the meta has changed. It cannot stand up to Sticky Web teams at all. Popular mons like Doublade put a complete stop to it. It offers ZERO defensive utility/synergy, and falls to common priority. The only blanket defensive threat that it can circumvent is Rhyperior, but the same can be said about Virizion and Sharpedo. I would argue that Ambipom is almost the better rodent now, as it at least has the super-strong Fake Out to deal with some offensive threats.
