And, yeah...I guess your Pokemon levels are okay, for most of da part. (Boost Exp aside)
...But still, you can't really say something easy nor hard when, you, yourself is 8 levels higher the gym leader strongest Pokemon. I'm just saying. LOL
And before you ask, NO...I don't Grind much when I play pokemon. If you don't believe me, just look at some of my Pokemon videos. :p
Anyways...since you said she dealt a decent amount of damage on you, I guess I'll let it be.
Not to mention, some of the other Pokemon in your party levels are behind like Meganium, Houndoom and Aggron.
My guess is, you used Ledian (I said this, cuz it was on Level 57) Floatzel and especially Altaria in the gym alot.
Anyways, good luck with the Lugia event. I increased it level and stuff...Wait, don't you halfta fight da Kimono Girls first...Good luck with them.
And what da hell? LOL You use Aggron as a HM slave...Seriously? That's first time I've ever seen one used like that.
Other than that, your pokemon moves are very good...Only thing I halfta say is...Ledian with Air Slash? *Trollface* Hey, that wasn't my doing.
JK...I know da deal, no biggie!
