-New Move (To be decided upon later if allowed) - as others have said may as well allow for new ideas to be inputted, even if it is a bit more of a headache. We could all be overlooking something(however, minute that may be).
-Meteor Mash - I keep thinking Iron Head would be plenty... however, steel is hardly an offensive typing. I just don't see a huge issue in it having this move, balance wise. It gives it some oomph without being overbearing.
-Explosion - Explosion really isn't what I see as a scouts purpose. Plus, as mentioned before the attack value on this thing is high. Combine Explosion with Meteor Mash and I can so see this guy being used as a sweeper. Probably not a 'unparalleled sweeper' but he possess immunities to fighting, normal, and poison. And resists a whole lot. Too top it off two of the types that don't fear explosion would not want to switch into one of this guys stabbed moves. Which would make it very good for sweeping(or at least if it gets both Mash, good ghost stab, and Explosion, that is how I will use it).
-Brave Bird - I don't see why not, but I don't really see a compelling reason for it. And a few reasons not for it. Namely recoil moves aren't a scouts cup of tea(usually). Basically if it gets Brave Bird it would strike me mostly as filler. So if you need a filler move go ahead, I suppose.
