Choice items are not very good but they're not terrible, either. Same with WP, which is probably the worst of its viable items. "Pretty well" is subjective, yeah?
Also you need to run maximum speed investment to outspeed Bisharp; it can be preferable to just use colbur berry.
I'd much rather get a 1.3 power boost to all my attacks and forfeit investment in HP and have a colbur berry, which could be totally useless against some opponents, and get to run some hp.
You are, again, comparing Aegislash to probably the third or fourth most broken thing to have ever been in OU.
Again, I just as easily could have used infernape as an example: Dragonite is a pretty good stop to Infernape, what if it runs hp ice or stone edge? you're basically done yipee.
Your entire argument is "it's not as versatile as this one really versatile thing so it's not actually that versatile." Aegislash can run like a dozen moves and items viably, it has a minimum of four good distinct sets, it has exceptional offensive and defensive capabilities, it can pursuit trap things, it functions great as a wall breaker and a staller, it can pick off weakened things with priority... I mean just how is it not extremely versatile?
I'm comparing aegislash to a versatile mon, and showing you how much LESS versatile aegislash is than a versatile mon. I don't see whats wrong with that.
Aegislash as a pursuit trapper is pretty sub par, it doesn't even kill latias as its switching out.
As I said earlier, unless the items are radically different and effect the actual choice of moves, (choice band vs choice specs) items really don't add much to versatility.
My definition of versatile is determined by how many pokemon can take you on comfortably. Despite your "exceptional offensive and defensive capabilitiyes...great as a wall breaker and a staller" mandibuzz is still an extremely powerful check to it and can switch-into 90% of everything aegislash can do. I don't care about what aegislash does, if a pokemon can still switch into it and handle it easily, then it's really not that versatile.
In relation to Cham/Garde/etc. it can usually only revenge kill them. That's what I meant. It has a lot of trouble switching in if you're using the band set, and the bulk up set won't beat all of them either. I'm very well aware of Bulk Up Talonflame, don't be so condescending.
Listen pal i'm not tryna be condescending but you made talonflame seem as frail as sharpedo or something, if you were aware of/used bulk up talonflame, I doubt you would've described it like that.
A burned Scizor is a lot easier to deal with than a healthy one. Yes you can't keep Garde in it but it means pretty much anything not weak to its STABs can switch in to it and win. Scizor is crippled if it's burned, Aegislash still has the option of Shadow Ball.
Also Jirachi is complete ass. I mean you really might as well bring up Metagross as a Garde counter.
Did you know that a burned scizor can beat rotom-w 1v1. Besides, aegislash still has to play a bunch of 50/50s with mega scizor as a burned +6 knock off will still do some big damage.
and jirachi is not complete ass, it may see some usage on the suspect ladder b/c aegislash is gone! Its other enemy, bisharp, will also drastically drop in usage because it often just helps the team by pursuit trapping aegislash for SD Mega hera/Mega Garde/Mega zam/mega cham etc etc. I mean half the reason to use bisharp rn is to just eliminate aegislash really, the other half is to abuse defiant and with deoxys gone, there's not going to be much of that either.
Not to mention tyranitar is far better at pursuit trapping lati@s than bisharp is.
Seriously, take a moment to consider why the king of BW OU was so bad in XY. In conjunction with steel's nerf, it was the rise of aegislash and bisharp that ultimately made it subpar. With those two largely gone from the meta, jirachi is a legitimate threat to prepare for.
Also, considering there are like two mons that can even take hits from mega gardevoir safely, and that one of them is a mega (zor), I'd think that jirachi is a perfectly respectable option if you don't wanna get your entire team shit on by mega gardevoir, which will probably be very common on the suspect ladder :I Unless you wanna rely on chansey ofc :/
Seriously outside of metagross, mega zor, and jirachi, what pokemon can even stomach its attacks?
It's the best way in that it is the easiest to fit on a team, the most viable by and far of Cham/Garde's counters and it works pretty consistently. Furthermore its presence deters the use of HJK no matter what pokemon you have out.
And yes I've used Sub Medicham, I'm pretty sure it's widely considered one of its best sets, not sure why you'd think I'd deny it's good.
Aegislash is the easiest mon to fit in any team so the first part doesn't really apply to the argument anyway.
And I never said that aegislash wasn't the most viable of mega cham's/garde's checks (AEgislash can't switch into fire punch, not a counter).
I don't really think aegislash is really a great mon to pressure the use of HJK in the first place considering how risky it is to switch into a fire punch.
It is for offensive and balanced teams. Slowbro, Mew and Cresselia concede too much momentum on offensive and some balanced teams whereas Aegislash slots in with relative ease, covering gaping weaknesses whilst posing a threat to the opponent. Mew and Cresselia aren't as popular as Slowbro (which isn't very popular to begin with) because they aren't much good apart from checking Medicham.
Honestly for offensive teams i'd rather rely on revenge killing them than trying to stomach their hits, because especially with mega medicham, if your opponent predicts and nails a fire punch, you lose the glue of your team. And slowbro is gaining tons of popularity fast; besides just b/c a pokemon isn't used often doesn't mean its bad.
And are you seriously suggesting the only purpose of using mew or slowbro is to check mega cham???
They do so much more besides that hello
