The only common physical sweeper who is likely to have Stone Edge is Tar. Salamance doesnt have it on his typical moveset, Lucario almost never has it and Rhyperior is BL. Ice is more common (though SR is unquestionably common).
Only Tyranitar? This is the 6th most commonly move in the metagame we're talking about here. In OU alone, I've seen Stone Edges coming off Aerodactyl, Breloom (admittedly never going to try its luck), Dugtrio, Gyarados, Heracross, Lucario, Machamp (also not so good without Scarf), Mamoswine and Swampert. Ho-oh needs speed EVs to beat a lot of those, though most of them are risky to switch in.
Besides, if Ho-oh really was that dangerous/common, things would start using Stone Edge more often, just as Vaporeons often run HP Electric for Gyarados. Things adapt.
Ho-oh takes less than 50% from typical Swampert's Surf. HP Grass may be chosen for surprise for Rhyperior and Swapmert, and yes, it may be inferior to Earthquake. But Zapdos struggles against Tyranitar, whom is scared off by Ho-oh's Earthquake and Heatran sucks against Ho-oh.
Swampert can learn Stone Edge and Roar (and when you consider how much Ho-oh takes from SR, this
is putting it in a lot of danger), the latter being very common. Tyaranitar doesn't switch out in fear of Earthquake, which doesn't OHKO, but Ho-oh is going to have to be pretty crazy to stay in on Tyranitar.
A roosting Zapdos is destroyed by Rhyperior's Earthquake. Ho-oh has at least severly hindered Rhyperior if it gets burned.
I don't think anybody would switch Zapdos into Rhyperior in the first place, let alone try to pull off a Roost. As for Ho-oh, it would be very unlikely to burn a Rhyperior; Rhyperiors would generally switch in on predicted Roosts and Thunderbolts anyway.
And it's impossible to compare Porygon-Z to Ho-oh, when there defense's, typing and movesets are so differently. Pory-Z isn't that common due to speed and bad defences. Ho-oh doesn't suffer the last problem. And blissey outrights walls Pory-Z. And yeh, Suicune and Milotic can beat Ho-oh assuming their healthy, but Blissey is more common than both and even with less than 50% hlth, still walls Zapdos. Want a spcsweeper to beat blissey, use trick which so many spcsweepers have - gengar, azelf, starmie, rotom and more, zapdos not included.
That wasn't what he said. He merely compared their speed stats, not what they do. Besides, if people wanted something like Blissey that could also wall Ho-oh, they could always use Snorlax. It doesn't matter that Blissey is common, because people could easily just start using things that could wall Ho-oh.
And if Sacred Fire pp is a problem, Ho-oh could have Flamethrower for surprise with a special sweeper set. it could even be a sunny day pokemon with solarbeam, which is so much better than Zapdos' HP Grass. it can be screwed by sandstorm, but that's not as common as it used to be (and earthquake can still be used for tyranitar). any rain dancer swapping in on Ho-oh's sun risks lots of damage from solarbeam (including Kingdra).
From personal experience, I'm seeing even more Tyranitars nowadays if anything. Its Pursuits are important for the likes of Azelf, Rotom, Blissey, etc.
Sunny Day outside of Ubers (and sometimes even In Ubers) is really poor, and Ho-oh won't change that. Sure, it would be a beast under Sunny Day, but it wouldn't get rid of any of Sunny Day's current flaws. What would the proposed set be? Sunny Day / Sacred Fire / Solarbeam / Roost?
I don't think anybody would run Flamethrower on Ho-oh unless they were doing a SubRoost set on a stall team.
Chris is me said:
I agree with this. In some cases, though, the future is predicable to anyone (for example, the sky will be blue when I wake up tomorrow). The debate is at what level of uncertainty do we place the bar? If 99 out of 100 think it will be Uber in 5 days, do we test? 90? 50? I'm in favor of a low barrier for things we've never tested, regardless as to whether or not the OP that proposes the test is making sound arguments all the time (he's been a bit off with a few of them admittedly).
We could make a poll and see what people think?
I don't think the thread alone is a good indication, as here it seems 50/50.
