Hey, I have an idea for trade evolutions. If the pokemon evolve through trade from their lowest stage, they evolve at level 20, and if they evolve via trade from their middle stage, they evolve at 40, in both cases providing they meet their requirements. So a porygon with an upgrade and a dubious disk can evolve at levels 20 and 40, a karrablast and a shelmet must both be at level 20 and evolve together, and a machop will evolve at levels 28 and 40. Sound good?
