Sorry about dropping the gwn4 stall topic. Truth be told, I'm rather weighed down by a lot of things and exams and whatnot so it cleanly slipped my mind. I don't like gen5 as a whole when it came to competitive OU because the weather wars ruined it for me, but if you will, I'll continue where I left off last time and talk a bit about Obistall a d gen4 stall in general.
Er-hem, now then. [QUALIFIER: the following assumes we're talking about gen4 stall only. See my previous post for the difference between stall then and stall now]
It's a common notion that defensive playing is thought of as something horrible. It's seen as a brain-dead, skilless way of sponging hits and accomplishing nothing at all. That, in my view, is a pity, since defensive play has its own strength. This principally was due to the fact that early on (REMEMBER: No team preview back in gen4) players have limited information about each other's teams, and therefore their prediction or strategic planning was limited to guesswork. A wrong guess with an offensive team spells a quick defeat, whereas defensive teams have more flexibility in that regard; they are more forgiving of errors and can be better used even when taking unforseen circumstances into consideration; in other words, defensive play makes the game stretch out a little longer so you can maximize the portion of each play that is prediction as opposed to unfounded guessing.
Contrary to popular notions, there is a considerable level of prediction involved in using a stall team. This is especially true in the case of stall vs. offensive teams (at least as long as the stall team is good; If the team in question is just a bunch of fat Pokemon who just sponge and do nothing else, like how teams of later generations have transpired, then yes, prediction is nigh on useless. However, when passive tactics such as Hazard Stack and residual inflictions are involved, prediction is key to net as many opportunities as possible to do so. There is where the true elements of caution and precaution feature; and there is where defensive teams cannot afford to lose their members. One can even argue that the need to anticipate and ably preserve such elements is more reliant on accuracy in prediction and planning than organising tactics with a fully offensive team.
As for the other scenario of stall vs. stall, it is true that prediction, that is to say, anticipation of the members of the opponent's team and their behaviour, is minimized. However, properly constructed stall vs. stall is probably the highest form of long-term thinking. There's a need to think several turns ahead to be able to do any lasting damage to the opposition, otherwise the match will wear on, as is popularly belived, into a deathly bore where one team is worn down no quicker than the other.
Then there's the aspect of pre-battle skill, not merely in-battle skill. Pre-battle skill refers to the art of teambuilding, which is even more crucial to stall teams, wherein it is necessary to have an answer for every kind of anticipated threat. Here is where Obistall comes in.
Obistall, as the stall team made by Obi, an old smogon doyen famous for crafting stall's popularity is called, is perhaps the most celebrated of all teams in the DPP generation. Pre-Platinum, it was hard to make a successful stall team without reducing it to Obistall, whereas post-platinum and post-salamence, this team and it's variants were the best or most perfect example of holistic stall. The team was especially responsible for Tentacruel's rise from the UU Tier to OU usage, as people discovered its niche in the metagame. The huge amount of thought and effort put into the team is apparent in the inspection of every choice made. This team combines all of the elements needed to create a "full" Stall team, and acts as an excellent example to illustrate the epitome of gen4 stall.
I will not repeat what has already been described fully, by the creator himself, so I'll link the team itself here, and leave the floor open to discussion and criticism. In my next post, I'll talk about a variant of Obistall that I have decided to be of good use when tested out in DPPt now.
