If you don't care about effectiveness, why would you care what anyone thinks? And if you DO care about effectiveness, why would you use anything but the most effective ones? Do you really just want to use a "gimmicky" set, just to go against the grain? What's the point? Your own satisfaction?
Personally speaking, I love the idea where a trick room + Focus Sash Shuppet kills an uber by doing Trick-Room then Destiny Bond. It won't win you any tourny, and taunt can ruin your day, but it is funny.
As to the actual debate: Satisfaction is unfortunately outside the realm of logic and debate. Logical debate can only prove relationships but rarely comes into use when the actual rewards/punishments of the system are not lined up between the debaters. While it may not be any reward to have a gimmick set to you Misty, I think it is obvious that there are battlers out there who wish to "break the mold" and have a set that no one has thought about before.
Pokemon is one of the few games available where exploring just for "fun" is possible. Assuming 60 attacks per pokemon (I pulled that out of thin air, but I can assure you that at least Banette has more than 60 avaliable attacks), then the number of combinations of attacks are a combination of 60 taken 4 at a time, or 487,635 different combinations of the same pokemon, not including EV spreads or items for each combination. Then of course comes Mew and Smeargle with well over 100+ things taken 4 at a time which are several millions of different movesets for each pokemon.
The fact of the matter is, the "fun" part of Pokemon revolves around this. The fact that there are literally millions of ways to put together a team (multiply the # of pokemon combinations with 2431522835, the number of 493 pokemon taken 6 at a time to form a team, then the number of items, EV spreads, etc. etc.)
Competitive Battlers try to simplify the game by cutting down this number of combinations. It is necessary to provide a proper analysis of the game. Really, no competitive battler would want to go through all of the movesets for all of the Pokemon... there are just too many "stupid" movesets like Gust + Tackle Pidgey or whatever.
A gimmick battler would on the other hand, want to prove this fact about Pokemon: that there are so many things that people do not consider and that there is still room to explore. Probably because Pokemon is currently seen as a child game that this impulse is here... but that is the best explanation I can come up with. That said, a "gimmick" set must do two things:
1. It must work in a competitive environment
2. It must surprise not only your foe, but the entire community
Tyraniboah would be a "gimmick" under this definition because it shocked the metagame, but that really is the "gold" that I believe gimmick users are looking for. They are really looking for the best set that no one has found yet.
Which is exactly the point of lurking more. Newbie is not a bad thing; nothing wrong with being new. There is something wrong with being new and posting a ton of crap movesets without ever thinking to see if they would actually work. "Lurk more" is a fine and correct thing to expect. This thread is sure as hell not going to be unstickied or deleted any time soon.
I can't say that this is unfair... but I think we honestly cannot expect ignorant newbies to know whether something is crap or not. That is the problem with being a newbie ya see... you really don't know when a moveset would work or not.
I understand the necessity of this thread, but there are just too many posts here that refer to the thread that prompted this one. I may disagree with this thread, but I'd like it to be effective. Currently, the majority of the thread (including my posts... I'm not leaving myself out of this) do not contribute to this thread really. I think locking this thread, stickying it, and deleting all the replies would contribute to its effectiveness.
