What if you try Flinging a boosting item (Ganlon, Salac, etc. Berry) to Driftblim while Driftblim is holding a Colbur berry (reduces damage taken from a super-effective Dark attack, also activating Unburden) and that will allow Drfitblim to Baton Pass out quickly turn 1.
If you use a fast Flinger, say Weavile, it could really work to outspeed foes. Remember, Drifblim is also Immune to Fake-Out so it is guaranteed to Baton Pass. Alternatively you could use Sneasel since it reaches 361 Speed and has Inner Focus, making it Immune to Flinch, or Alakazam with Fling since it also has Inner Focus.
Or using Swagger/Flatter on Lum Berry Driftblim as it Baton Passes.
Alternatively using Swagger / Flatter with Lum Berry, or Safeguard on any teammate can be helpful , or if the teammate has Own Tempo. (Hey, it beats Helping Hand + Life Orb...) +2 = x2 which is greater than +1 = x 1.5 + .3 = x1.8. x2 > x1.8
Don't forget Accupressure, since unlike the other strategies, it works past Protect / Detect. Accupressuring Bibarel as it Protects can prove useful due to Simple.
And even more so if Bibarel uses Endure as it holds a Starf Berry during the Accupressure. Gaining +8 to 2 random stats (+4 each) but that last bit is highly situational.
