A gimmick is anything that is completely different from a Pokemon's normal fare or a completely different Pokemon entirely. These sets can catch the opponent off guard and throw off their battle plan while advancing yours. Netting a surprise kill or two can mean the difference between a win and a loss. This is not like Expert Belt Latios or something where you're running a standard set but switch up the item and maybe a move with the same general goal. This includes Pokemon such as mixed Shiftry and Eelektross; Taunt Fighting Gem Sawk; Psych Up Metang, Regirock, and Regice; and so on. These are Pokemon tailored to lure and defeat specific Pokemon. Sometimes these sets go on to become popular or somewhat standard, and sometimes they have very niche purposes for certain teams.
Now that we've defined a gimmick, let's talk about the purpose of this thread. This thread is the place to post your gimmicks and to discuss the role of gimmicks in competitive battling. Another good discussion point is the use of them in tournaments vs. the ladder, where it's the difference between winning one battle and consistency. How do these gimmicks affect defensive teams? Are there defensive gimmicks? What works? What doesn't?
As a last note -- what I'm looking for in posted sets:
[sprite]
Pokemon @ Item
Trait: Ability
EVs: EV Spread
[x] Nature
- Move 1
- Move 2
- Move 3
- Move 4
[A short description of how the set works—around a paragraph is good enough]
For example:

Primeape @ Choice Band
Trait: Vital Spirit
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Close Combat
- Assurance
- Ice Punch
- U-turn
This is a Primeape set that I used in my most recent (serious) RMT, which was used to lure in and defeat Musharna with the use of the very situation move, Assurance. After some hazards damage, if Musharna switches into Primeape's Assurance, it is 2HKO'd, opening a sweep for itself or Jynx later on in the match. Obviously this isn't the perfect gimmick; Musharna users won't always switch into Primeape because of U-turn. But because my team doesn't carry a Skuntank, having another way to defeat Musharna without anything on my team being paralyzed or without losing my Liepard to a stray Signal Beam can be incredibly advantageous.
It's also very important to note why your set is usable over standard ones. This doesn't just go for the Pokemon itself, but also for other Pokemon that could fulfill its role far better. For example, you could use Curse Musharna with Zen Headbutt instead of the standard Calm Mind set, but there's little to no reason to do this, as you ultimately end up losing to almost all of the same Pokemon you did before, plus more. Also, please have experience with your sets before you post them! It's great to think up of something that could be good, but without actually using it, you'll never know for sure. I've had plenty of ideas that were great on paper just not work at all in practice.
That's about it! I'll probably archive some of the sets in this thread here in the OP, so get to posting. :)
