Here's a set I've bee tinkering around with:
Mollux @ Life Orb
Trait: Dry Skin
EVs: 128 SAtk / 228 Spd / 152 HP
- Acid Spray
It results in 369 HP / x Atk / 202 Def / 363 SpA / 246 SpD / 245 Spe.
It's set to be one speed point above 72 Spe Gliscor sets. The idea is to have Rain set up with SR, and use Acid Spray to weaken a switchin. Mollux takes LO damage which is then nullified by Rain, and finishes with Thunder or Flamethrower. Recover allows it to come in on a free switch and get back to full HP, or avoid LO death in non-rain weather. It's a kind of hybrid Bulk/Speed set that has slightly more SpA than a Timid set. In general I've found it hits a sweet spot between bulk, speed, and power and is quite versatile without doing too much at once.
That said I haven't had a ton of time to test it out on multiple opponents, but it's been pretty solid for me.
Had a squeaker with Pwnemon and the team this is on. It should give a good glimpse into what the metagame is like.
