In regards to Magneton i agree with you that using it as a bulky attacker is fairly effective you made a lot of good points, also i'm sure there are even people out there that just assume it has Magnet Pull and are not paying attention so they think they are trapped when they really are not XD. Magneton is very versatile i find it very ingesting that at one time that was the final evo for that particular tree, sometimes i even forget all about Magnezone being the final Evo for the Magnemite family. Also for Magneton he does have the advantage of sleep talk/rest if you choose to go the specially defensive route and be used to take any sleep moves plus he even can survive a Moltres LO flamethrower with stealth rock damage if i remember right for the specially defensive set and OHKO back with T-Bolt. Also another interesting fact about Probopass is that it has access to the ability of Sturdy as well much like Steelix, he seems to have a bit of everything but at the same time for me yes i would have liked him to have a little more offensive capabilities, but i think he would still be a bit interesting to use, that Rock/Steel typing is a blessing and a curse at the same time for him XD, but yea i just like trying new things and seeing how effective they are in action.
