>>22932457All Escavalier needs is at least one decent ability - Analytic would do very nicely - and maybe some form of Recovery. I don't really think any of the existing healing moves would really make sense for it though. Recover itself could maybe work if you view it as repairing its armour, but I always saw it more of a Psychic thing, even though it's a Normal type move.
Bug/Steel is fantastic typing, it's got good bulk on both sides, and its movepool is definitely usable.
