Yeah yeah... ting lu can ruination it and cause it to not want to switch in well... great tusk can knock and swith out and all of a sudden ur taking a lot more damage.. even smth like lando-t or garchomp which dont threaten it as much (it cant threaten lando-t much) and even then garchomp usually can just eq it down... + u have teammates to counter hatt to.... while they also have teammates hatt isnt ORAS mega sab lvl of fucking over removal.
"if your Hatterene takes rocks, you probably screwed up somewhere"
uh huh... much easier said than done
Unless Ting-Lu is heavy slam, you can just draining kiss/leftovers the ruination. Also, teams with Ting-Lu probably do not feature a hazards setting Gliscor, just saying.
I'm looking at the rest of your list of rockers, and I must say... most of these are awful Gliscor partners. Nobody... let me emphasize that real quick.
NOBODY. NOBODY is running Garchomp + Gliscor or Gliscor + Landorus-T. I hope I do not need to explain why this is a poor choice.
Great Tusk is the only legitimate one you could say, and even then, most are ice spinner and not knock off. Plus, draining kiss deals a lot. Besides, not many people run Great Tusk + Gliscor, since that is also a typing + physical ground type overlap.
I'll try to explain why half of the mons you've suggested aren't actual counters in the first place.
1. take heart manaphy does NOT like switching into spikes (that you set yourself) and if it happens to be KO gliscor and gets knocked on the switch then it's incredibly to wear it down with HALF decent offensive pressure since it doesn't have the consistent lefties healing it.
2. i hate to break it to you but hatterene is just straight up not the answer u think it is gang. Hatt legit takes a quarter from an uninvested eq (MINIMUM) and all gliscor has to do is switch out to its teammates like a dirge, milotic, heatran that's a fairy resit and hatt is forced out with ease. (yes milo is basically a fairy resist at this point). Also wearing down hatt is stupid easy. it has 0 reliable recovery and if you don't want to get spiked or hazard spammed on you practically have to throw it into battle to make sure that it and it's teammates don't get rundown by the spikes/ rocks users. And if you don't predict correctly then hazards are going up and you're using hat to stop those exact hazards. So in reality the mindgames "do i click hazards or not" are just skewed in the attacker's favor.
3. corv is an unserious mon whether you have a gholdengo or not. in general it's a huge momentum sink that flails around bulky defensive teams OR it's a pokemon that gets overwhelmed pretty easily against offensive teams that threaten it. Simply put, corv feels like a do-nothing mon in most match ups and I do not rate this mon highly.
4. MG cleff does shit on gliscor but spedef gliscor can make it waste moonlight pp which can be costly if you're playing against a bulky team that NEEDS your clef to manage the 8 moonlight PP that it has. but yah mg clef is by far the best gliscor counter.
5. for things like balloon ghold and heatran are literally do nothing about the spikes gliscor sets down. Like you're acting like we're playing a metagame where we can't just switch out of the MU. there are bulky waters everywhere like emp, milo, mola that don't give up momentum and allow for a pivot into a pokemon that threatens it out. and as for milo it just beats both those 2 mons outright. and remember gliscor very well could have just spiked left and then next time all of your other mons are getting worn down.
All of your counters "work" against gliscor to a certain extent for sure. there's a reason why gliscor didn't get quickbanned to the shadow realm instantly.
However, we play a 6v6 metagame, and gliscor's ability to wear down it's checks and counters WHILE making progress for your teammate's checks and counters is what makes it problematic. That is why every Ban voters have been screaming there's no GOOD counterplay against gliscor.
hope this actually makes sense mate :-;
1. Yeah, Manaphy doesn't like spikes, but Manaphy finds itself on more offensive teams, where spike setting opportunities are a lot more scarce.
2. Sure, you can go into something like Skeledirge. That's probably the only one I would honestly accept. The issue with Heatran is that Gliscor teams often cannot fit hazard removal and, thus, cannot fit a leftovers reliant mon (or a mon that just gets its balloon popped and taken out with spikes). As for Skeledirge, only knock off Gliscor makes you hate Skeledirge because with 2 turns of lefties and draining kiss on Skeledirge, you healed everything back up. Rinse and repeat for 16 earthquakes and now, Hatterene infinitely sits on Gliscor.
3. Corviknight isn't really that bad as people keep considering it as. It has good pivot and utility as well as serving a purpose as an early game Kingambit answer with rocky helmet and body press. It definitely has its uses, and if it was an unserious mon, it would literally not be in OU and, before you say that it's Gliscor's fault, it was still OU before Gliscor too. This isn't even a mon that's dodging UU right now like Landorus-T; it's consistently a top 20-25 mon. For reference, September's usage stats (before Gliscor) had Corviknight at #19, which is not bad at all, and currently, it's #21, which isn't bad either. I get this isn't an incredibly accurate representation of how good Corviknight is, but it should prove at the bare minimum that it isn't bad.
4. Personally, I do not like the moonlight sets and prefer the wish sets, but the moonlight sets that do exist can run moves like calm mind with leftovers to threaten even spdef Gliscor. Wish sets do not get PP stalled that easily, if at all.
5. I mean, heavy duty boots and offensive teams also exist. Neither of these care that much about hazards unless you have a good knock off user, which you probably have some way to absorb knock off, such as Corviknight, Clefable, your own Gliscor if you really wanted one, or potentially Great Tusk. Before you say that "Gliscor forces boots," Gliscor really doesn't; we've been doing the same before the DLC for the exact same reasons as right now.
