Yeah, I thought that would be the case too, but when I got my Electivire today (Laka helped, and also gave me the Lake Trio and Rotom... ) I wrote down the stats of Electabuzz prior to the trade. When I got it back I found the Special Attack and Special Defense hadn't changed at all, while Attack had gotten a major boost and so surpassed Sp Attack. Speed went down, and HP went up a bit. It's a pleasant surprise, though, 'cause now he can effectively use Ice Punch.
My team is:
Torterra
Rapidash ( Megahorn)
Bibarel (named Bidoof )
Crobat
Electivire
Girafarig
It's apparently a good team, since I beat Laka with it.
I've got a Shuca berry or so. I'll try it out.
BtB
Oh good.
Well... if 'Vire fails again, try bringing out Torterra. It should fare reasonably defensively against Garchomp, which you should attempt to nuke with Leaf Storm in combination with a White Herb, if you can get one. Crobat should also be able to survive against it; it lacks anything supereffective, though, so just hit it with Crobat's strongest Flying move.
If this advice fails, I won't be surprised in the least. After all, it's coming from me.
