Lucario or Skarmory?

[TheSignOfLibra]

Okay, I've had my very good Skarmory, Silver, on my team since I first got to Ula'ula (fourth Pokemon caught to be a contributing member of my team). Anyways, Silver helped me get through the Elite Four and become Champion. But then I found a Riolu, which I named Cobalt. Anyways, I'm considering replacing her with Cobalt, once he evolves, but I'm not sure. Is it worth it? Or should I keep on Silver for those pesky fairy types that Cobalt would have and every other member of my team currently has a bit of a difficult time dealing with?
If it helps, here's my team (besides Skarmory):
Absol
Lycanroc (Midday Form)
Typhlosion
Tsareena
Primarina

I say keep Skarmory. Regarding Fighting type moves, I think you have other Pokemon that can learn those.

Keep Skarmory. A physical wall would be helpful since most of your team is frail.

I'm inclined to say go for Lucario because we're namebuddies (:D), but Skarmory is better for your team for the reason strangerhypno stated.

I'm with the others in that you should stick with the Skarmory. It also has a benefit of being a physical wall with very minimal weaknesses, which could definitely benefit your mostly frail team.

Okay, thank you! I'll just keep Cobalt on long enough to evolve him for the Pokedex, because I hate trying to find Pokemon through the SOS thing, and go back to training Silver. Again, thank you all!

I would normally say Lucario but I think Skarmory is a better value to your team so your Pokemon could use a fighting move.
