Meteor Mash should be allowed as a solid STAB option. Not allowing it because of the 20% chance for an attack boost is silly. It's not going to be sweeping even with a Life orb and 1 attack boost. Steel is not to threating of an attack type.
I am solidly against
Earthquake if Heatran and Magnezone are supposed to be counters. They shouldn't have to resort to being scarfed to threaten it.
Bone Rush and
Dig are ground moves that are mediocre options that I would be okay giving. I'm fine with the scout being walled by steels to be honest. Knowing that their opponent might U-turn to a Dugtrio would make them think twice before switching in a Steel.
Explosion is a no. I would encourage people to go look at the Speed of the Pokemon that get it. Now on anything that is fast look at their base Attack power. Azelf and Mew are the only outliers that are fast on their own and have a good base attack.
Explosion on something this fast is too good. It doesn't really help it with it's duty of scout and it really makes it lean towards more of a suicide lead (even if it doesn't get Stealh Rock or Spikes)
Volt Tackle, Power Whip, Seed Bomb,Stone Edge even the already allowed
Aqua Tail... come on. Are people just throwing out moves they think would be cool? Why would it get these moves? What precedent does it have? Since when does steel grow vines and have seeds? Stone Edge and Aqua tail have very little precedence with Ghost or Steel typing. I know this is Create A Pokemon, but these options seem too much off
Body Slam, and
Brick Break are moves that I feel are ok. Body Slam is annoying with it's paralyzation and would help with scouting. You may not want to send in your Agilgross or a speedy sweeper on a CAP7 spamming Body slam. Brick Break is about as powerful a fighting move it should get IMO.
Cross Chop is therefore a no along with
Superpower.
Even though they are of little significance with something with base 55 special attack, many ghosts get both Thunder and
Thunderbolt
Gengars movepool (explosion aside) is a good outline for what we should be choosing for moves IMO. Many of the Steel options that we have looked at have already been mentioned.
Also Magmortified I've rearranged the allowed list in a order that I think most people will agree makes more sense and makes it easier to read. Feel free to use it.
