Gliscor shut all those Pokemon down due to its Volt Switch immunity, U-turn resistance (it takes chip damage from it), and passable bulk. At best, prediction from AV Conkeldurr removes the Toxic Orb from the switch and Hydro Pump does not guarantee a KO when Stealth Rock is off the field, and often the core's Stealth Rock setter is Lando-T and it is hapless from Gliscor, whose best option is to U-turn away from the core into the periphery before it can set up Stealth Rock. Ice Punch without a status doesn't KO Gliscor, although Life Orb + Iron Fist does.
I do not know the calcs, but one can put special defensive investment to ensure it survives uninvested Hydro Pump at full health or probably after Stealth Rock. Survival is more important than the amount of health to Gliscor since it has the Ground and Electric immunity and good speed to spread Toxic if it decides to sacrifices itself.
First off, gliscor should be faster than both rotom-w and conkeldurr. This means that the sub-toxic sets, the most common and efficient one, beats both of these one on one.
Gliscor risks dying with or without SR from hydro pump and the sp. def evs are generally not worth it, especially when sub-toxic beats rotom-w anyway.
I slapped on a Kyurem-B with a Rotom-W, Lando-T, and AV Conkeldurr core. It obviously needs a "free" switch. Kyurem-B can handle Stealth Rock even with Life Orb, but Toxic would be lethal.
Gliscor will be using substitute and protect more than toxic, its not too hard to predict a proper switch-in. Once kyu-b is in safely, you can set up a sub with ease (nobody runs max speed gliscor) and then just spam ice beam. Sub lefties is the most common (and imo the most effective in this meta) so no worries about life orb.
Even if it is in, it would only force Gliscor out into a check. At best it would force Gliscor out. Kyurem-B is too ponderous and does not like to switch out; I intend to use it on a stall-breaking run when its checks has been removed.
This is not really a great argument. When you force something out, you're hitting the switch-in for some damage, wearing them down and hopefully weakening it with your good coverage to the point where it can't switch in on you again. You say that you use it as a stall-breaking run when its checks have been removed but honestly, unless you have a pink blob its tough to take him on, especially on the switch and it still has a sub up (you should get out of gliscor vs. kyu-b with a sub but its fine even if you don't) It's not as if kyu-b sweeps, you're just supposed to soften up the opposing team with him. The way you word it really sounds like you're trying to sweep with him, sorry if I'm wrong.
Genesect is only as a good as its partners. It can been seen as part of a core, or the periphery of the core. I do not primarily regard Genesect as a U-turner as I do not highly value its defensive traits so see much defensive synergy with Rotom-W or Lando-T, so I do not see it as part of a Volt-Turn core with Rotom-W. I am more likely to use Hydro Pump prophylatically than risk the Volt-Switch being predicted.
Scarf genesect is crappy, but lets try to defend it the best I can.
The idea behind is fast u-turn is
to threaten out the pokemon you're facing with a possible SE move. This surely isn't hard considering genesect's great movepool. Scarf genesect thus performs well because he outspeeds the frail pokemon he can maim with coverage moves. Of course, instead you will be u-turning, which is where the advantages of a fast u-turn kick in.
With a fast u-turn, your opponent has two choices:
1) Take a heavy hit (you should be in on a pokemon which you can maim to maximize the efficiency of fast u-turning. Thus pokemon with great coverage are also good users of a fast u-turn)
or
2) Switch out
2) is obviously safer, but that's why u-turn works. You slowly wear down the opponent's answer to this genesect (hopefully this pokemon also walls your sweeper, so that when it has been weakened with all the u-turns your sweeper can muscle past it) and all the while you threaten your opponent's pokemon with a wide variety of coverage moves.
Now obviously its not all rosey and pink for scarf genesect. On a pokemon which you don't hit super effectively, it won't be doing much damage at all. Genesect's power is simply underwhelming when it cannot hit SE, and while it usually can with its great coverage moves, it's just too weak overall.
Which is where things like banded genesect and expert belt genesect come into play.
Let's describe each one and talk about how both are better than scarfsect.
Banded genesect:
Basically you come in on a resisted hit or safely, like a scizor locked into BP for example. You come in, threaten flamethrower from a scarf set, then hit the, say, rotom-w switch in with a clean u-turn.
Well, what happens when you stay in with scizor?
This is where it gets a little tricky. If you do u-turn, that means that you will have to switch into something else that doesn't mind a banded scizor bp, which is sometimes annoying to find mid or late game. So while you have to be careful of u-turn because you're not slower, which is where the disadvantage of a fast u-turn comes in:
If you don't threaten a pokemon out with a possible coverage move, then when you use u-turn the incoming pokemon must take a hit first.
This isn't good, any pokemon appreciates a safe switch-in more.
But the trick behind banded genesect is firing off powerful u-turns. Sure, u-turn pivots, but its a whole new problem
when that pivoting move is threatening.
Let's see a scenario. A sylveon can take a u-turn or two. But something like a rotom-w doesn't really want to take a powerful u-turn.
The opponent has two options:
1) Let rotom-w take a powerful hit but get a hit off on the switch in (cuz you're faster, remember?)
2) Let sylveon take a resisted (but still powerful) hit, and then lost momentum
It's essentially a lose-lose scenario if genesect is in on something he threatens with u-turn! You let the poke take a heavy hit or you slowly weaken your answer and lose momentum. This is why banded genesect is so good, scarfsect can't apply this type of pressure.
Ebelt genesect is pretty easy to explain really.
Ok, so lets say that you clicked ice beam on a garchomp. That's a bit obvious, and your opponent doesn't want to risk it (even though he has fire blast on his chomp, because the general assumption is that genesect are scarfed) so he switches into ferrothorn. He then assumes that you are locked in, and since (let's just say that you don't have the sp. att boost) it didn't do much he wants to get some leech seed going, or maybe set rocks, and because he thinks you want to switch out because you're choice locked and ice beam isn't doing much, its likely he's gonna stay in.
Well, the point of ebelt is to surprise! So, in an ideal situation where the ferrothorn doesn't have protect, you could just use flamethrower and nab that surprise KO! That's all ebelt really does, lure "safe" switch-ins to stay in believing your choice locked to then nuke them with a strong coverage move. Obviously this works best if a choiced set is the most common (ebelt lando-t or ebelt rotom-w won't be using ebelt to much because they're not usually choiced), and scarfsect is definitely the most common thing out there.
Now that we're done with genesect, I want him to be gone for teambuilding reasons. It's more or less clear that scarfsect, while crappy, fits on basically any team and it requires little thought to just smack a scarfsect on an incomplete team and play with relative success. It hinders the creative teambuilding process and makes the meta super stale, which is never fun. Just think, when and if genesect is banned, people will actually have to think about what scarfer to use. Just a distant dream, I know, but I can dream.
On another topic, I would like to bring up a potential issue with the suspect ladder.
We are almost half-way to our deadline to get reqs (which are super tough goddamn) and the highest people on the suspect ladder are still only around 1400. If the suspect ladder gets up to 1700 at all, I don't think there'll be more than 10 people on there.
Just a minor concern, I might be underestimating how fast elo can inflate.
