Protect + Attack on Talon/Aegi/fastmon is what you are calling outclassed. Wait, really? No. No. Yes...Really!?!? Show me one example of how talonflame does damage and makes itself invulnerable in one turn, allowing it to literally revenge kill any mon without reliable recovery. You talk about dual link? Dual link takes even MORE damage from rocky helmet on both sides. Does it really matter whether or not BB + protect is outclassed? Nothing else makes it invulnerable while attacking, right? Protect + BB or Protect + Acro can make mons without reliable recovery, priority, rocky helmet, or high bulk literally unviable. The fact that a mon can consistently eliminate / force a switch on so many mons that should be viable is the definition of overcentralization. King's Shield + Shadow Sneak is even worse, and you said as much, but talon is no better. Protect + icicle spear is even worse because you can only touch it every other turn, and have only such a high chance to break through anyways. Its total aids. Anybody for king's rock iron head + zen headbutt jirachi? Yeah, let's not. Get this shit out of here.
Thank you for being the first to actually give a convincing against flinch strategies. I'm still not 100%, but given that I don't use these strategies nor do I think that they are viable, I wouldn't mind them being banned for the uncompetive factor. What do I have to lose. I still think stall and all archetypes have ways around it, but I guess I won't complain not having to prepare for it if people are mad about the RNG (Even though it should always be prepared for naturally). But this won't stop Scarf Jirachi, and Fake-Turn which is worse to deal with and more competitively viable, other than being weak to Rocky Helmet.
So go ahead and ban King's Rock and Razor Claw if you hate it that much for being uncompetitive. I can't really complain.
But I'm still not convinced on Protect + Attack.
Shadow Sneak + King's Shield is a completely different story and I feel is/should be the main/only reason for anyone wanting to ban Protect + Attack links. This combo effectively gives Aegislash 60/150/150/150/150/60 stats all the time if you just keep spamming your link. King's Shield also decreases attack making Boost + Attack links less power full against it. This is why Shadow Sneak + King's Shield is used more then the unresisted power of Sacred Swords + Shadow Ball.
Talonflame with Protect + Brave Bird however is not all its hyped up to be. I'm gonna quote you here;
"Protect + BB or Protect + Acro can make mons without reliable recovery, priority, rocky helmet, or high bulk literally unviable. The fact that a mon can consistently eliminate / force a switch on so many mons that should be viable is the definition of overcentralization."
People need to realise that this is exactly what Brave Bird + Aerial does, only arguably better as the opponent needs even more bulk, as you effectively have Gale Wings + Parental Bond. Your problem is Talonflame, not Protect Talonflame.
People have argued that the reason Talonflame with Protect is uncompetive is that it effectively gives Talon "Free Turns", which is simply not true. It gives Talonflame another turn to live, it doesn't give it a free turn. Lets take one of the most effectively talonflame check and powerful megas, Mega Tyranitar with its Dragon Dance + Stone Edge combo for example. Tyranitar switches in to a Protect Brave Bird, next turn proceeds to use Dragon Dance + Stone Edge. Talonflame uses Brave Bird + Protect again because why not? Its a free turn right? So by the end of that turn your Talonflame has taken damage from Recoil and Sand, while doing minimal damage to Tyranitar and letting the opponent get a free Dragon Dance. If anything, Tyranitar is the one getting the "free turn". And given that you are never gonna win that war you either sack Talonflame or switch out giving away more free turns.
Any team that doesn't want to have its ass handed to it by 90% of the teams on ladder need at least 1 reliable Talonflame answer. Mega Tyranitar with Dragon Dance + Stone Edge, Aggron with Head Smash + Rock Polish, Relicanth with Head Smash + Rock Polish, Mega Ampharos with Heal Bell/Electric Terrain + Volt Switch, Rhyperior with Stealth Rock + Roar, Heatran with Stealth Rock + Roar, etc, etc.
And you no what's funny about all of these? They eat up Brave Bird like its nothing, and set up stats or hazards while threatening to KO Talon all in one turn. Who is getting the free turns? It certainly ain't talonflame.
Another interesting thing about these Talonflame checks/counters is that not one of them has reliable recovery. You know what wears them down a lot faster than Protect + Brave Bird? Brave Bird + Aerial Ace. Isn't that funny.
I believe it was mentioned a couple times how Talonflame with Protect can beat Mega Diancie 1v1. Who cares? Has anyone actually seen a Mega Diancie? Lets talk about pokemon that are actually relevant shall we?
Like Clefable. Standard Unaware Clefable can't switch into Brave Bird + Aerial Ace Talonflame, or it will get 2HKOed 100% of the time. But Protect + Brave Bird talonflame fails to 2HKO Clefable, meaning Clefable gets a free switch in and can start boosting with Cosmic Power + Moonlight. Note who is getting the free turns here.
Toxic Heal Gliscor has a decent chance (59% or guaranteed after SR) to get 2HKOed by Brave Bird + Aerial Ace Talonflame, but is only 4HKOed by Brave Bird + Protect. Also note that given its bulk and Poison Heal, Gliscor is able to run more sets than just Toxic Stall. I've actually seen a few running Defog + Stealth Rock Linked, then Roost and Earthquake as fillers. Not only does this set get "free turns" to set up SR vs Protect Talon, is also has no chance in hell of dying to Talon because it is running Roost.
Let me list all Talonflame Switch ins on the Checks Compendium and put them into the categories of "can switch into Protect Talon only", "can switch into Aerial Ace Talon only", "can switch into Both" and "can switch into neither. Note that this is Sharp Beak Jolly Talon, as it lets it switch moves for Aegi, and isn't Paralysed by Whimsy.
Switches into Protect Talon only: Gliscor, Slowbro, Mega Aerodactyl.
Switches into Aerial Ace Talon only: -
Switches into all Talonflame variants: Heatran, Mega Slowbro, Mega Manectric, Rotom-W, Tyranitar (Mega), Hippowdon, Omastar, Alomomola, Empoleon, Rhyperior, Tyrantrum, Aggron (Mega).
Cannot switch into either Talonflame: Mega Diancie, Garchomp, Kabutops.
Note that all of the counters that can switch into either variant are worn down much faster by Aerial Ace Talonflame.
Any pokemon not 2HKOed by Brave Bird with reliable recovery and can threaten to KO check Talonflame. There are a lot more pokemon that can 2 Brave Birds than there pokemon that can take 2 Brave Birds and 2 Aerial Aces.
Also just lastly I'd like to point out that there other Protect links that are also neither broken nor uncompetive and can actually be considered quite innovative.
Protect + Extreme Speed Dragonite is one I've seen used a bit, and is a fantastic pokemon to revenge kill Talonflame as it can guaranteed 2HKO it with band while out prioritising and Protecting itself from Brave Bird. It isn't at all broken because Extreme Speed only has 80 Base Power, isn't boosted by STAB, and is resisted by common types used to check Talon and Fake Turn. Also the "Free Turns" concept I've all ready stated is false.
Another one which I've used is Sucker Punch + Spiky Shield Cacturne. As it is a terrific stops to things like SD + Outrage Scarf Chomp, Fake Turn, Flinch users, Aegislash, and just dual physical attackers. A great blanket check to stop sweeps, and sets up spikes with the switches it forces. Is it OP or uncompetitive? No. Is you don't attack it you get free turns to do what ever. It is countered by the most common pokemon in the tier, Talonflame. Which can Out prioritise, OHKO, eat Seed Bombs and is immune to Spikes.
In conclusion: Ban King's Rock and Razor Claw if you have too, but it won't stop Scarf Jirachi and Fake-Turn.
Also don't ban Protect + Attack links. Consider banning Shadow Sneak + King's Shield link specifically.
