alright, so here is my reqs in case there is that one guy that doesn't believe me
But basically, now that I have got reqs, I want to go into depth about Bisharp.
So basically, Bish is a strong dark type. This is nothing new as we have really strong dark types like Hydriegon, Krook, M Shark, etc.. Unlike any of the above dark types, it has steel as a secondary which allows it to break through fairies a lot better. This also allows it take a hit from latias better than any other mon on the list above and give it 9 resistances. But ,as we all know, it is the defiant ability that makes people question if it is broken or not. So what this means is that these 3 characteristics make Bisharp broken.
1. It is a strong Dark Type
2. Steel secondary typing
3. Defiant
These are not enough to make bish broken. These also really do not account for Bish's weaknesses also. So anyways, Im going to analyze all these aspects of Bish.
1.
Strong Dark Type
Not gonna touch on this too much since no one has really brought this up as a main reason to banned, but I have heard people say on the past forum that its stab sucker punch was too much. While yes, it is the strongest sucker in the tier, strong priority inst a new thing in the tier. Most HO teams have 2 steel, water, and/or ice resists for Mamo, crawdunt, and scizor respectively. So this will just force offense teams to have 2 or 3 dark resists rather than 1 or 2 like some teams were doing prior to Bisharps arrival. It will make teams change some aspects of team building, but literally every tier changes in UU history has had this happen (exaggeration, but u get the point). Bishs presence will just make Dark checks more necessary on a team, and that alone doesnt make it broken. If Bish was broken by this logic, then Scizor would be broken. Cause as we all know by now, if u do not have a good +2 Sciz answer and a good Sciz switch in, youll likely be screwed. Same thing applies to Bish as well.
2.
Steel secondary typing
So the steel second typing is a blessing and a curse for Bish. Offensively, it is great for bish. It allows it to hit fairies extremely hard as the only fairy not super effective to it is the keys (and bish checks the keys). Also, defensively it helps out bish as it resists 9 types. With the amount of choiced attackers, it allows it to set up on a lot of stuff. However, it does have its flaws. Its typing allows (most) fighting types to take advantage of it. Priority fighting moves take advantage of its low speed and 4 times weakness to fighting. Then also, Coballion and Chesnaught is a great answer to Bish and Coballion is not a good stand alone pokemon. Then before anyone says low kick Bish, where does Bish have room for it. SD is part of what makes Bish really scary, and pursuit allows it to be a good AV user. So bish just doesnt have room for low kick. Bish without an AV has trouble switching into, well almost anything that it doesnt resist. (Ill show later). But overall, its typing has more advantages than negative, but also has some majors flaws .
3.
Defiant
While there is no denying it is the best defiant user, it still has some weaknesses. Here are some calcs of common defoggers.
Here is some examples of common defogers
0 SpA Altaria-Mega Flamethrower vs. 0 HP / 4 SpD Bisharp: 188-222 (69.3 - 81.9%) -- guaranteed 2HKO
252 SpA Life Orb Latias Draco Meteor vs. 0 HP / 4 SpD Bisharp: 164-192 (60.5 - 70.8%) -- guaranteed 2HKO
0 SpA Moltres Flamethrower vs. 0 HP / 4 SpD Bisharp: 314-372 (115.8 - 137.2%) -- guaranteed OHKO
252 SpA Life Orb Hydreigon Draco Meteor over 2 turns vs. 0 HP / 4 SpD Bisharp: 269-316 (99.2 - 116.6%) -- guaranteed KO in 2 turns after Stealth Rock
0 SpA Empoleon Scald vs. 0 HP / 4 SpD Bisharp: 126-148 (46.4 - 54.6%) -- 98.4% chance to 2HKO after Stealth Rock
0 SpA Florges Moonblast vs. 0 HP / 4 SpD Bisharp: 151-178 (55.7 - 65.6%) -- guaranteed 2HKO
0 Atk Scizor U-turn vs. 0 HP / 0 Def Bisharp: 94-112 (34.6 - 41.3%) -- guaranteed 3HKO
Basically, these calcs are here to show that u can not just mindlessly switch Bish into defoggers. Also, people are starting to adapt to Bish being in the tier. People are running rapid spinners as there are not really any good spin blockers. And then they are running defoggers that can beat Bish 1v1. Examples are moltres, rotom-h, fire move hydriegon, M stoise, offensive Kiss and Malt. While this annoying at the moment, It is not impossible to run defog and not be afraid of Bish at the same time. Not to mention, Bish often has to get multiple plays right in a row in order to take full advantage of +2 boost from Defog.
So these characteristics were clearly not enough to make Bish broken back before OU stole Bish as basically no one considered it broken then. The only major thing that would impact are Keldeo and Gliscor being gone. However, I feel that this is a lazy arguement. First off, Keld isnt even nearly the best check to Bish (+2 LO sucker does 60 min). Also, gliscor had to be poisoned, before it came in as Bish could get rid of the best passive recovery in the game. Obviously, if these 2 were in the tier, Bish would be worse. However, this is not like the Amoongus and Breloom relationship at all. Neither of the 2 above mons counter Bish like Amoongus counters Breloom. Also, people seem to forget about what can counter Bish now. Gligar is naturally faster than Bish and can do some nice damage with a stab EQ.
0 Atk Gligar Earthquake vs. 0 HP / 0 Def Bisharp: 170-204 (62.7 - 75.2%) -- guaranteed 2HKO
Also, Keldeo wasnt even the best swords of justice answer to Bish. Coballion is and always will be a much better answer to Bish. Offensive Coballion can take a +2 Knock and Sucker from Bish (also can take a +4 sucker) while offensive Keldeo could never dream of doing the same thing. I could list off more Bish checks, but that has probably been beaten into ur head already.
One final point, is that Bish will undeniably have a big impact on the tier. However, literally every mon in A+ or S has a big impact on the tier. So this will just be a mon that can be annoying that is also really good. I think this is a bad mentality to have for a tier. While it can be argued that this is what happened to M Venu, I think we should just not repeat the mistakes made in that suspect test again (if you feel thats what M Venu ban was).
So Tl; DR
Bish's traits do not make it broken. Also, No keldeo and Gliscor just makes Bish better, not broken
Edit:
Also if anyone wants to know the team I used, just PM and Ill probably give it to if you arent a dick
