I'm a fairly new player to Pokemon Revolution, and I think I've made a huge dumb mistake during my very first run in Kanto. While having troubles in the second battle against Giovanni in Saffron city, I noticed that I have amassed 40k, this is when my mistake happens. I made a deal with someone, in return of 40k, This person gave me a level 100 Rattata to help me sweep Giovanni and the rest of the Kanto gyms. It worked, This Rattata helped me single handedly beat Giovanni and the last 2 gyms. But a problem arose when I went to the Elite Four. This Rattata, although pretty powerful for a Rattata, Was not able to take out any of the members of the Elite Four, and the problem is, The rest of my Pokemon are severely under-leveled for the Elite Four, (lvls 40-52), due to me lazily taking out every gym leader and trainer leading up to the Elite Four with my Rattata. So not only are my Pokemon under-leveled, but there's little to no trainers for me to level them up. My laziness quite literally doomed me to life in Kanto, and I'm trapped, I attempted to dig for nuggets and do tasks for rare candies, so I could sell them in attempts to buy more Pokemon to help me, but to little avail. Any tips? I'm completely lost and I feel like a complete idiot and I feel like I made the dumbest rookie mistake ever.
