Delta Treecko Line: NEED HELP

Another thing, is the line meant to be pure steel? I think that that steel/ dark could be a potential typing and it is a pretty decent typing that I personally would use in a playthrough. Another possibility could be steel/ fire? I just think that if a specific typing would be given to it now, I could make it look more like a delta, rather than a recolor, no offence to the creator of this. Does anyone think adding sharp claws would be a good idea?

The steel/ fire typing just gave me an idea, what about doing a whole trio of Hoen starters? They could be the type that they are normally weak to and then another one, maybe another type triangle? Perhaps steel/ice/ ground? Mudkip would be ice/ grass and Torchic could be ground/ water. Steelman2004, maybe you could design them?
