Great idea, but an elite four trainer would have to be way higher than x3 your level, or you'd just beat him like you would Dragon Tamer.

Since it's the elite four, each trainer has six pokemon you have to defeat, but you can't be able to get your pokemon healed afterward (that's what makes it hard in the game). The first trainer should be 3x, sure, but then 4x, then 5x, then 6x, and you get a badge if you beat the second, a better badge for third, and the super badge if you beat all four trainers. Sounds very hard though, we'd need items that can max a pokemon's health. 9-10/10.

goo idea . not too easy but not to hard at the same time. good thinking
