I like that set too, but I prefer using Spikes as well. Probably over Shadow Ball, but I have never really made a good team with it. I know a Showdown! player known as Warawanai uses it with moderate success, though (the reason I say it's moderate despite him being upfront on the ladder is because I have infact never lost to him).
Now I have an interesting topic to bring up- I started thinking for a while yesterday, it was about weather in Ubers. Almost all teams utilize a a weather (or even two) on their teams- and while weatherless teams are good (Skyless World made by my fellow clan-member Bossness is excellent) I noticed a strange pattern. This is large generalization but:
Sand teams have and advantage against sun teams.
Sun teams have an advantage over rain (!!!) teams.
Rain teams have an advantage over sand teams.
I have found this to be a bit correct to be honest, after countless of battles with all team archetypes. Of course this is generalization, I could still beat a less experienced player using a sun team with my rain team. Anyway, I might have to explain how I came to my conclusion.
Sand teams have and advantage against sun teams:
This one is quite straightforward- Hippowdon and Tyranitar a both decent answers to the most threatening sun-based Pokémon Ho-oh, and Hippowdon also checks Groudon and sets Stealth Rock. Sun offense (which I consider the only viable sun-team archetype) usually use Espeon with Focus Sash or Cloyster using the same item. Sand Stream breaks the possibility of living any hit, which makes getting the rocks up much easier. Also, concerning Arceus-Formes used on sun- the three best in my opinion being Rock, Water and Fighting, you can clearly see and advantage here. The Arceus-Figthing I am talking about is using the moves Judgment, Toxic, Recover and Stone Edge (its best overall set) and can easily send Ho-oh flying, toxic Arceus-Ghost, and destroy E killer- common Pokémon on sun offense. Arceus-Water and especially Arceus-Rock are also big roadblocks for sun teams as both utilize a Calm Mind set that cannot be walled by Ho-oh in the sand (in Arceus-Rocks case, Ho-oh won't ever have the chance), meaning Groudon has to switch on Arceus-Water, taking damage before Ho-oh can beat it. If a sand team uses Arceus-Grass, then the sun team might win, but as I said Arceus-Grass is incredibly overrated and is very liable to fall to rising stars of BW2 Ubers such as Ho-oh, Genesect, Kyurem-W and Latias, making it worse than in BW1.
Sun teams have an advantage over rain teams:
This is a bit vague to be honest, but Ho-oh is a big reason why this can be true. Life Orb Ho-oh completely tears rain stall apart, Specs-Kyurem white is also great against these teams. Not to mention Palkia. The sun which can be set up in Kyogre's face can sometimes provide a very easy set-up for Arceus Extremekiller or Calm Minding Arceus-Ghost. I also consider rain stall being much better than rain offense, because as strange as it sounds, I'd rather use sun offense than rain offense as it is much better. Some rain Pokémon are good, some are really bad against sun to be honest. Here is a list of common rain mons and how they fare.
Good:
Omastar- Doesn't mind a Groudon switching in to remove the weather, unlike Kabutops. Omastar has Shell Smash and attacks from the special side so it can actually come in on Earthquake-less Ho-oh.
Dialga- is hard to Magic Bounce. But an Earth Plate Groudon can wreck it before it can move.
Kingdra- same as Omastar to begin with. Threatens Dragons walling its Water-STAB.
Excadrill- Even though it has Mold Breaker SR, it is slow and can be KOed by Ho-oh. If it gets up rocks it's actually decent.
Bad:
Kabutops- Unless the weather war is won, it can't do much because Groudon can switch in on it relatively easy. Sun teams won't mind the surprise Rapid Spin as much, because they are mainly focusing to keep Stealth Rock off their own side of the field, rather than spikes-stacking.
Ferrothorn- OMG it is balls vs sun. A liability, because Ho-oh gets in for absolutely nothing. Forry sets up on it, Xatu stone walls it, these are common mons on sun.
Tentacruel- if it gets a layer of toxic spikes maybe. But it has trouble with Latias, fast Groudon, and Ho-oh.
Rain teams have an advantage over sand teams:
I think this might be true because a combo of Deoxys-S+specs Kyogre+Genesect can really do work here. First turn, Deoxys-S vs TTar- Ttar must crunch as Deoxys gets rocks. Then Kyogre comes in. Nothing enjoys the water spout, Giratina is almost 2HKOed, and Latias is a liability because Genesect. It is quite obvious why rain works well vs sand, considering specsOgre is incredibly dangerous when the weather never decreases its STAB move's power.
Now these are just some thoughts, and obviously you can alter different weather archetypes to combat what can beat you. What are you guys thoughts?
) beats rain stall, rain stall beats sand stall, and sand teams regardless of its archetype beats Sun offense/balance as long as it has Arceus-Rock or Arceus-Water (Arceus-Grass variants are, I would say, actually at a disadvantage against Sun offense/balance though), but I personally wouldn't generalize further than that. As you mentioned yourself, rain stall loses to Sun offense/balance largely because of the former's passivity combined with the fact that it often has no way of defending against a Life Orb Ho-Oh at all, but I don't think the situation is that bad for more offensive rain teams, since they can actually offensively threaten Sun offense and balance teams (much moreso the former from my experience) in return. Rain stall beats sand stall from my experience not just because of what you mentioned, but also because a battle between a rain stall team and a sand stall team inevitably comes down to a stall war, in which the former has one extremely huge advantage over the latter: Rain stall teams typically have an incredibly useful Toxic Spikes user in Tentacruel, whereas not only do sand stall teams tend not to utilize this entry hazard, but they more often than not do not even have a Pokémon to absorb Toxic Spikes. And when Hippowdon, Tyranitar, Arceus-Rock/Water and other Pokémon that don't have a way to cure their status get poisoned, the user of the sand stall team is placed at a significant disadvantage against rain stall. And additionally, the dangerous thing about Toxic Spikes is that as long as a Pokémon has no way to cure its poison, all it has to do is step on the field once with Toxic Spikes up, and that entry hazard would have done its job, even if it does get removed from the field later on in the match. And you also perfectly summed up why sand teams with Arceus-Rock or Arceus-Water (or just about any team with them, though they are by far most common in sand teams) beat Sun offense/balance.
