I think we've heard enough about bulky waters by now. They counter just about all the sets without Thunderbolt (but only by Toxistalling or stat-upping), but the mixed set will probably be quite common so perhaps not great switch-ins.
Hippowdon might be able to switch in on just about any move other than Sacred Fire, but if running Stone Edge a Rooster would beat it so it could only SR / Roar or Toxic to cause it a lot of trouble. Pretty much stating the obvious, but yeah.
Max attack, positive nature (probably Lonely if it ran that) and Life Orb Ho-oh does 36.19% - 42.62% to standard Hippowdon. Leftovers could protect it from a 2HKO after burn.
Back versus Lonely Ho-oh, Burned standard Hippowdon does 55.24% - 64.87%. Stone Edge Hippowdon could actually be a very dodgy way to deal with SF / EQ / Thunderbolt / Roost Ho-oh. If it uses Roost, Thunderbolt or Earthquake Hippowdon could come in and OHKO it, and if it started trying to stall with Roost [which already has the aforementioned flaw of a full HP Ho-oh getting hit hard by it, though that wouldn't be a problem on LO Ho-oh thanks to ss] Earthquake hits it for a lot. Not a particularly reliable counter, but it is another thing that could still work to some extent.
@TVboyCanti, the first half of your post is more or less "Guess what, bulky waters don't like Thunderbolt!", but you've convinced me that Porygon2 and Ludicolo aren't counters to sets like that. Tyranitar shouldn't be discredited as a counter just because it takes a lot from Earthquake, as Sacred Fire and EQ are the only two moves Ho-oh has that Tyranitar can't switch in on and deliver an OHKO back. An Umbreon with some Defence EVs can still work imo, though Burn is dangerous.
Also, you do mean that the three pokémon you listed as solid counters are the only ones out of the group you listed, right? I somehow can't see Cresselia taking much, for example. 18.92% - 22.30% from Life Orb Lonely Sacred Fire on 252 HP / 108 Def standard Resttalker. 20 HP / 252 Def standard set takes19.43% - 23.06% from SF and can even carry Reflect to make that nothing, and it can cripple with paralysis, toxic poison or possibly even spam Charge Beam and hope it wins in the long run, when SF is out of its 8PP.
Anyway, I know people are eager to get the Latis (even though SpecsLatios Draco Meteor makes everything shudder) tested after Skymin and Deoxys are done, but after that I don't think it would be hard to fit Ho-oh in. Unless Manaphy and Darkrai (guessing this is going off anyway) are considered less centralising, which I would have to disagree with.
