One question...Why Crush Grip? Why not, say, Return? Isn't Return just better in every single position except when you're hitting them from full HP? Even then, it's only 6 BP lower: will that really prevent your ridiculous ATK titan from killing anything?
Good question. Before I get into this, let me explain a few things about the rest of my team:
> I use the Helping Hand strategy on almost half of my Pokemon and implore it directly with Regi after Drifblim switches out/Baton Passes.
>There are no entry hazard moves on my team. I focus primarily on self-boosting and less on debuffing the opposition. (Return would be more useful if I have Stealth Rock in play for example or change the weather).
>On a side note, Crush Grip is fun to use because it is exclusive to Regigigas and looks very cool on PBR.
Here's the way I see it: A Helping Hand-boosted Crush Grip OHKOs many walls like Weezing, Gliscor, Leafeon, Donphan, and even Hippowdon (on a good day:). Return does not have enough power to OHKO Donphan or Hippowdon even with the helpful 1.5 boost. The main purpose of Crush Grip is to trash healthy walls into oblivion.
>As pointed out by TheMaskedNitpicker, there is almost a 20 BP difference between Return and Crush Grip. Return's best potential is 102 while CG can get up to 121 on a max HP opponent.
I see your point that Return would be more useful if the opponents HP is down, but after a Crush Grip, not many walls can live through a second move (Dusknoir and other ghosts obviously cannot apply here). CG leaves Cress with only 40 HP and why finish it with an attack that only hits one opponent (Return) when Rock Slide KOs the weakened one and can possibly flinch/kill the other one at the same time?
I'm sorry that this is so long-winded for a simple question. I didn't realize I had been typing for this long.
Baron, I'd go with Shadow Ball in Drifblim's last slot because Regigigas doesn't have any really good ways of putting the hurt on Ghost-types. Also, for maximum defensiveness on the Drifblim, you should put all your EVs in Defense and SpDefense. Its base HP is so high that you get higher overall defenses that way.
I completely understand what you are saying about ghosts; however, I have other members on my team that can take care of them (I'm starting to think I need to complete this team in the RMT forums :). Rock Slide hits Gengar and friends hard, so Dusknoir has become the main issue here. On a side note, that double-def boosted Baton Pass can make an average sweeper a deadly tank.
I also see your point about Drifblim's defenses, but I don't really have the time to train another one now. The EVs are completed and the purple balloon can hold its own decently.
Since you know my strategy now, I would love to demonstrate it to you in a slightly unbalanced battle sometime haha. I'll PM you when I get a chance to escape from work.
Thanks for all comments everyone.
