Why is your aron level 11 this late into the game?

Answer 1

First thing first, you need to severely level up your entire team except for Swellow. Now, Tate and Liza both have a level 42 Lunatone and Solrock. Now, onto your team. Movesets need some serious improvements, but I would focus on Sableye. With Sableye being a Dark Type, it is Immune to Lunatone's only attacking move being Psychic. However, you do have to worry about Hypnosis, but not too much. With this being said, we just have to focus on Solrock. With this team, I would just Level Up Shuppet to survive and use Night Shade on Solrock to wear it down and KO
with help from your team. Also, teach Sableye Shadow Ball. It's better than Astonish. There are many more improvements I can make, but if you want them, let me know. Alternatively, you can teach Swellow Steel Wing to cover Solrock. Hope this helps!

Oh okay. Is there a quick way that I could level up my pokemon. (instead of just walking around and battling wild pokemon. Like so I don't have to grind for 2 hours.)? EDIT: Also, do you think it is a good idea to level up Sableye to?

I would go to Granite Cave until you get you Pokémon into the 30's, then go to Route 117.  And definitely level up Sableye to at LEAST 40.  As this was my main strategy with Sableye, make sure to.  Also, could you mind clicking the green checkmark next to this answer?

if your playing on an emulator you can just cheat in rare candies and get them all to at least level 37-40 so your not exactly cheating but your getting it done more quicker
