I just wanted to say that you may have noticed a theme with my suggestions. They're all Fire type Pokemon, and I intend to keep it this way for as long as possible. It's not easy to thing of good ideas when I'm focusing on one thing lol
The thing with Camerupt is its safest switch in is Rotom-W (and to an extent, Azu). HP Grass avoids the OHKO (or even close to it), which means Rotom can outspeed and KO it back. Now, screw that. Nothing is safe anymore. Energy Ball is also boosted by Sheer Force. HP Grass is horribly weak compared to it (I'd do some calcs but I'm on my mobile). Every time Camerupt comes in, something dies. It may be slow, but under a Trick Room there is literally nothing that can safely switch in. This also means you're able to run another Hidden Power if you really need to, but Camerupt's great STABs say otherwise.
What are the problems it has? Is it too slow? Trick Room, and it also gets Rock Polish if you really want to get into it. Bulk? Lol it's actually pretty bulky after it Mega Evolves. It can eat up hits pretty nicely if it wants to. Its typing? It's typing is actually pretty good if you ignore the Water weakness (which now you can!), and it has pretty much unresisted STABs that hit like an absolute truck. It's biggest problem is the lack of reliable recovery. Maybe Slack Off would have been a better choice, but just use something with Healing Wish and you're all good. I guess Chansey still gives it problems, but that's one thing that barely stops it. My idea is a focused one, but Trick Room teams will appretiate the extra support. I'm not saying it's a fantastic idea, but it sure helps. (It's better than Probopass lol)
Other opinions:
Simple Audino -
Swoobat lol
I wouldn't say it completely outclasses Clefable, since Fable has Unaware, meaning opponents can't boost up with you, and it also has Moonblast over Dazzling Gleam. That may not seem like much, but the damage difference is evident. I thing Audino might be better if Greninja gets banned, so it wouldn't have to worry about Gunk Shot. Seems pretty interesting, but I'm not a fan since I just don't like Audino as much to begin with. It really is bad that it wastes your Mega Slot, which can be used for something more helpful. I mean, simple Calm Midn is powerful, but you can really slap Simple on anything that has Calm Mind and call it a day. Cresselia? Simple. (Holy crap that one is actually good.) Clefable? Simple. See my problem? Not to mention that any drops it gets as well will be doubled. It's a double edge spears that I'm not a fan of.
Levitate Probowhatever- no
Still really outclassed, and I really see no reason in using it. Doesn't it get Magnet Pull? Isn't that better anyways? I have no idea what this thing even is so I can't say too much.
Plus it's literally ugly as shit
Unaware Registeel - Kinda cool, but I don't like Steel as a defensive typing anyways, since it's weak to a lot of common attacking types like Fire and Ground, and Char X just plan beats it outright, but it's kinda cool that it can't be Toxic'd, so it's kinda a better Quagsire in a way. Actually, no, scratch that. It's a worse Quagsire. Quag has a better typing, reliable Recovery and isn't complete Taunt bait because of Scald. Still not that much of a fan tbh. I think something like Heatproof would have been much cooler, especially considering Unaware makes little to no sense in the long run, since it's pretty smart in the movies, and I hate the fact that it's breaking away from the trio like Kurona said.
Sorry this is so short and poorly worded. I actually left the area where I had internet for an hour and had all that time to type this up lol. I'm most likely going to be on my mobile for the week since I'm doing a lot of shopping for a New Years party since I can drive now. I'm also celebrating that I got Bioshock, Assassian's Creed and Titanfall, so don't expect me to be on a lot during this lol
