Wow, psychics disappear because people use lopunny? dang, thats genius. Also loppuny is so overrated, it doesnt necessarily beat aegi/ unless it has encore. otherwise you get the minus 2 or switch out on aegi/ neither of which sounds too nice. And people aren't going to stay in again and take the -2 hjk. No, your opponent can switch. So loppuny doesn't even beat aegi/ without encore. so this is a really stupid argument.
Going to assume you meant People use Lopunny because Psychics disappear with Aegislash around. And the problem isn't just whether or not Lpunny checks Aegislash, it's the fact that with Aegislash around to either beat or just force out her checks, Lopunny runs trains over everything else, hence the talks of "Aegislash + 2 Aegi Checks + 3 filler" team template, with Lopunny being under filler and still offering a soft Aegi check.
If lando's check are limited to psychics you can run knock off. Lando is threateing without aegi/ support, and bisharp is a better pursuit trapper overall. People are crying out for a lando suspect regardless, it has nothing to do with aegi/.
Running Knock Off means Lando doesn't have the 3-move coverage he needs to pull off his boosting (RP/CM sets). And if Landorus is already dangerous enough to consider suspecting him, why not do that before bringing down something that creates a clearly mutual beneficial partnership that can break teams so easily.
And yes, Bisharp might be better as a Pursuit trapper, depending on how you define better in said context, but Aegislash does a whole lot else (defensive synergy, wallbreaking with his STABs) on top of still being a sufficient Pursuit trapper. By your logic, why would I run Skarmory when Hippowdon takes hits better as a tank (Physical or Mixed)? Because Skarmory offers other things that can make it fit better on my team, and in Aegislash's case, he fits better on almost any team than a substitute.
lando has no hard counters besides cresselia, talon can set up easily and can beat its supposed counters with natural gift op. Rotom has so many different sets it can run. All of these are just as threatening as aegi/ is. and your last sentence doesnt make much sense. No gards run hp rock, but many run shadow ball, not just to beat aegi/ but because they tend to have an extra moveslot regardless. and why can talonflame not fire off an attack in that scenario? talon even gets u turn, making the role of a pivot easier to fill. See the flaws in your arguments yet?
- You yourself just said Landorus has no hard counters, so not sure why you suddenly are using it as a sarcastic example against the Pro-Ban side.
- Talonflame still has a decent number of hard stops, and Natural Gift sets tend to be Lures since losing both its item and a moveslot is a notable hit to Talonflame's effectiveness against the Metagame on the whole.
- Exactly how many sets does Rotom have? I only know Phys, SpD, and Trick Scarf. And unlike Aegislash, who checks most of the same things and just puts in active work differently, a Scarf Rotom-W isn't going to check most of the things Phys Defensive Rotom-W checks.
Barring that, not sure where you get that all 3 of these are "as threatening as Aegi is", considering, for starters, you can't even throw them onto any team archetype and just expect them to work regardless of set (Landorus-I is outclassed defensively by Therian, Talonflame can't quite have utility and offensive presence at the same time, and Rotom is way too slow for offense). Aegislash goes on a team, it WILL put in work, it's just a matter of how you want it to.
Gardevoir doesn't run HP Rock because she's a Wallbreaker, and Talonflame is not a wall, so beating him ain't her job. However, being unable to beat a powerful defensive mon in a core IS something a Wallbreaker needs to be ready to do, hence Shadow Ball. And please explain to me what the hell Gardevoir is running Shadow Ball for besides Aegislash? Just because she has the free moveslot doesn't mean that it's put to good use for Shadow Ball over Taunt or WoW for the couple stall mons she can't just break through manually. Ghost isn't particularly good coverage because, like Dragon, it doesn't hit many types for SE damage, hence why you mostly see it as a STAB option because STAB power means you can afford neutral damage. There's one or two exceptions, like Alakazam, but that's because he can't break opposing Psychic types, which Gardevoir has little trouble with using Pixilate Hyper Voice. She is giving up that moveslot that covers literally nothing more for her besides Aegislash. At the very least Ground coverage in EQ for most Pokemon hits their STAB resists super-effectively.
Pivoting also requires Talonflame to take a hit coming in and be able to pressure the opponent into switching out. While he can do the former, the latter isn't easy with meh Bulk and a SR weakness. Come back to me when Talonflame has 60/150/150 bulk and 13 resists/immunities to go with that U-Turn.
Not seeing the flaws in their argument, but seeing them in yours.
i already talked about why loppuny is not broken, but let's see why fairies and psychics are still usable.
Oh, that's right. You can switch out on aegi/. GENIUS! You say how chomp is still usable in the current tier, well psychics and fairies will still be good in the aegi/ metagame. You give no reasoning as to why they wont.
Congratulations, you saved your Fairy/Psychic by switching. Nevermind that
A) Forcing them to switch is probably what Aegislash was trying to accomplish
B) Aegislash has a free turn to either Shadow Ball, boost on SD, put up a Sub, Toxic the switch in, etc.
The reason Aegislash eradicates Fairies and Psychics from the ladder isn't solely for killing them, but because in trying to switch them out, he gets a free turn, something you do not want to give to a mon that Versatile and powerful.
Rotom, lando, clef, tran, and gliscor all have so many roles. Want me to list them? Clefable and gliscor in particular have a shit ton of viable sets, and even heatran can run stuff like magma trapper or spdef. Does that make it broken? aegi/ can run similar sets to heatran, and i think that is a great comparison. Neither one is broken. So you rejecting that comparison doesn't have much ground, but I've rambled long enough regardless.
Clefable and Gliscor run different sets, but they don't ultimately change their role/effectiveness too significantly: Clefable still lacks offensive presence without boosting: whether it's Magic Guard or Unaware, or Cleric, it's not hitting too hard naturally. Gliscor is a tank and Stallbreaker, but retains vulnerability to powerful special attackers even on the special sets and just a bit of moveslot trouble with coverage on the SD set.
Heatran has roles, but similarly almost always has his own issues, namely his speed, decent number of weaknesses for his resistances, lack of recovery, and ultimate inability to break somethings like Bulky Waters without using very specific sets like Power Herb Solarbeam. Most of the traits I listed apply to Aegislash, except the last one: Aegislash's multiple sets let it beat more things, but it already handles a ridiculous number of Pokemon just by virtue of being Aegislash.
