[Any ways of faster leveling?]

Hello guys, as the title says I'd like to know If there's a way to level up my pokemon except for wild pokemon. Any remathable trainers?

I need it to prepare my party for the Electric Gym leader (West gearen) cause actually my team is: Feraligatr (Lv 62) Taloflame (Lv62) Vikavolt (Lv56) Golem (Lv55) Dartrix (Lv28) XXX Empty slot (I use it for TM slaves)

Thank you in advance

Same here and I don't even have an Itemfinder.

Use the teleport pad and re-enter that area with the latest patch (to be sure it's fixed), if you do you will have 4 ariados and when you go in the spot right to the girl you will finish it (remember to push down the log on the right near the teleport pad)
