I feel that Mega/Life Orb Scizor also might be good, with Technician-boosted bullet punch, but you might wanna have a U-turn to have a more synergised team swapping gimmick and, if you have him, have access to Pelipper when they pull out a fire type.
P.S. I wanna know some viability things about Raichu-A.
-Is Stoked Sparksurfer preferable over Life Orb? A special nuzzle is great, oh, and did I mention it's BP? It's an electric nuke with 175. But I feel it's been dragging Raichu down in power overall.
-Is Thunder a good idea when running with Pelliper? If I do, he gets more firepower, but at the cost of being more reliant on teammates. 70 accuracy is really bad. I don't know if 20 extra % for paralysis and 20 more BP is worth it.
-Again with the team synergy thing, should I put Volt Switch anywhere in Raichu's moveset?
