I would bring Camerupt and Rampardos (once I get the EC/RC to evolve it and the DC/RC to give it Sheer Force) to Frozen Vault. Both would be holding a Watmel berry, as I haven't really bought enough items. If I wouldn't have enough for Rampardos, I'd use Krillowatt in that slot instead. (Same item, given I have Natural Gift on Krill.)
I would bring Krillowatt (follow me+Water STAB for Rain/Thunder abuse) and Rampardos (same conditions as for Frozen Vault) to Wildfire Plateau.
Can't really say I'm ready for Stormrage Depths. My Riolu is far from evolving (and Heal Pulse is amazing for raids but Riolu sadly doesn't get it,) and I could use Krill, but if it starts BEFORE Mountaineer officially receives its nerfing/alterations, then Syclant would be a viable choice.
