Right, since we're on the subject of Bisharp, I'm going to say something really outrageous. Remember when I said, Deo-D approaches S? I don't think it does anymore.
Deoxys-D for S-rank.
I have not gone mad.
If you've ever played the higher ladder, you know what Deosharp is, and probably struggled with it too. That style of HO, that litters your field with caltrops and makes your checks to ridiculously powerful offensive threats non-checks because they're taking 18-25% damage switching in and probably paralysed too. It has been taking the metagame by storm in recent times with its terrifying efficacy, and with its biggest obstacles M-Lucario and Genesect gone, it is right now probably the most powerful influence on the meta.
If we're talking about Bisharp in context of this team-archetype, in which it most commonly features, I believe, it is a mistake to attribute the massive success of these teams to Bisharp himself. While Bisharp is a great offensive powerhouse, and it will devastate your team for clearing hazards at the wrong time, in the end is it just one component of Deosharp. Without multiple hazards Bisharp's strongest trait loses relevance, turning it into another slow, frail physical sweeper with an unreliable priority move. The real motor of Deosharp is not Bisharp, but
Deoxys-D.
Let's take a look at the definitions of S-rank and A-rank, and see which one best describes Deoxys-D.
As a support Pokémon and a dedicated hazards lead, Deoxys-D, when it enters the field, controls the dynamic of the early-game; it almost never gives the opponent free turns. To analyse this in a
"Guide to Making the Perfect Lead", I'll reiterate the most common moveset.
Deoxys-Defence @ Red Card
Ability: Pressure
EVs: 252 HP / 4 Def / 252 Spe
IVs: 0 Atk
Timid nature
- Stealth Rock
- Spikes
- Taunt
- Thunder Wave / Magic Coat
- Stealth Rock and Spikes: Step one - shouldn't need explanation. Set up SR and stack Spikes.
- Taunt and Magic Coat: Step two - work against opposing leads. Taunt will prevent slower leads from setting up hazards themselves, and in addition prevent their own Taunts and the hated Toxic poisoning. Deoxys-D's quite decent (for a lead) natural speed serves well to do this. Had it not been for Magic Coat, Prankster Taunt (by which I mean Thundurus - sorry Sableye :^( ) would have been a big thorn on Deo-D's side - and Deo-D possesses just the right move to prevent this.
- Red Card: Step three - make the opponent pay for trying to kill you. Deoxys-D is probably one of the bulkiest things in this metagame; the list of things, that can OHKO 252/0 Deo-D are as follows:
- M-Heracross' Pin Missile;
- CB Heracross' Megahorn;
- Crawdaunt's Knock Off;
- LO Bisharp's Knock Off (81.3% chance of OHKO);
- AV Escavalier's Megahorn (81.3% chance of OHKO);
- CB Tyranitar's Crunch (75% chance of OHKO);
- LO Aegislash's Shadow Ball (50% chance of OHKO);
- Only six mons (not counting the mega), and only three are particularly common - and basta. Nothing else can kill Deo-D before it sets up at least two layers hazards. CB Scizor can't do it. Gengar can't. And even the KO's from Bisharp, Tyranitar and Escavalier can be avoided by using an even bulkier spread with Bold nature and defence-EVs. With anything else than the list above, what do you get for trying to kill it as quick as possible? Instant phased, maybe to something without SE attacks or even a wall, allowing Deo-D to set up another layer for free. Combined with Step 2, the overall effect is "damned if you do, damned if you don't". Getting three layers of spikes is ridiculously easy this way.
- Thunder Wave: Step four (optional) - additional support. Things in HO hate being revenge-killed, so what better way to fix this issue than crippling one of the revenge-killers, making a non-issue for them? Even the full paralysis chance, while not to be depended upon, helps out sweepers by potentially giving free turns.
Why S-rank for Deoxys-D? Because unlike the A-rank supporters, which could potentially give free turns to the opponent, Deoxys-D allows very little room for counterplay. You are guaranteed at the very least Stealth Rock and one Spikes layer, probably more; step 2 above shows, why fast Taunters, even Pranksters, don't cut it as counterplay. Because of this, it is extremely easy to use. Probably the only thing you have to worry about are those six things, that can OHKO you - and you can always predict a Pursuit from Bandtar and stay in, getting it Redcarded and allowing you more free hazards, or just lead with something else than Deo-D and double-switch. Magic Bouncers are a full stop to Deo-D, but then again, how oft do you see Espeon in a better match, let alone M-Absol? Aside from being niche mons at best, they are extremely frail, therefore hard to switch in with such offensive pressure in HO (Bisharp sure loves switching into Espeon lol)
But what about support? You can't just kamikaze your Deoxys, you'll get your hazards defogged away! But then again, don't already S-ranks Pinsir and Charizard require support in the form of hazard control? Deoxys is something like this, but of the opposite end in the spectrum. Deoxys-D is most commonly paired with something provoking a "chilling effect" against Defog, and probably a Spinblocker too. Bisharp is the most common one, but it's not the only Defiant user. There is also the less common Defiant Thundurus (another S-rank) which is, in my experience at least, even more effective against deterring Defoggers; Mandibuzz and Skarmory might try to tank a Bisharp, but they won't dare give something with SE STAB a free Swords Dance!
On the other hand, simply applying constant offensive pressure can be just enough to "prevent" a Defog or Rapid Spin. It's how a lot of HO operates; be relentless enough to not give any free turns to defoggers or spinners. Many teams don't carry the full monty of Deo-D/Sharp/Slash; they might carry just one of Slash or Sharp, and sometimes even neither. Things like Bisharp just makes it easier; after all, even if you've got the free +2, your hazards are gone. But you're applying a tremendous amount of offensive pressure in exchange for this. But they can't ever do this without Deoxys-D.
