Drifblim @ Starf/Petaya/Salac Berry
Timid/Hasty [252 HP, 252 Speed, 6 Special Defence] / Unburden/Aftermath
- Charge Beam
- Substitute
- Hypnosis/Shadow Ball/Explosion
- Baton Pass
Stupidity ahoy. No one expects Drifblim to baton pass anymore, especially when it takes on the appearance of the standard sweeping set at a glance. Hypnosis isn't necessary, but can help you get your sub up. The strategy is fairly simple, sub down to starf, hopefully get in a charge beam or two, and pass your boosts off. Come back in as a sacrifice to Aftermath or Explode on something lategame and help set up your sweep if the first attempt fails.
Options: Petaya vs Starf vs Salac is about gambling, really, and what you want to pass boosts to. If you want to set up a pass midgame, on a balanced team, as I'm wont to do with Drifblim, starf works nicely. Salac is probably the most optimal option, and in this case you should consider running Unburden. Unburden also works quite well with Explosion, which no one seems to remember it gets. Petaya Berry gives you another special attack boost to go with Charge Beam, and is probably best to give to something fast, possibly scarfed. Regardless of the berry, your strategy is mostly the same.
Your third move, however, is a big deal. Shadow Ball lets you play for the sweep, and rarely will opponents expect your fourth move to be BP instead of HP Fighting until they've fallen into your trap. Do your job, draw out your counter, and pass EARLY, don't get greedy with charge beams - you'll almost never get more than two. Explosion is a panic button: if you didn't get any charge beams, subbed down to unburden, and don't think passing a +1 boost to your sweeper is going to do better than blowing up, blow up. It's also fun if you're using Starf and get an attack boost - nobody really expects their Drifblim counter (often Registeel) to be blown to hell by +2 explosion. Hypnosis is the "safe" option, which can help you get more free turns. There's really not much more I can say about hypnosis - it's there, it's inaccurate, but when it works it gives you free turns.
