This is amazing! (I could only see this now - didn't had time to see the other posts on this thread, sorry) A haunted suit of armor or chains are proably the best ideas for a Ghost/Steel, however, I would like if its design could be adapted so that it could have Levitate. Apart from the Light-type, a Ghost/Steel is probably something that the community desires most - unlike the Light-type, the Ghost/Steel Pokémon is actually likely to happen. Competitively speaking, we need better spinblockers, and such a Pokémon is the ideal candidate. However, we also need better ways to remove hazards.
