Rule of thumb: Ranged champions always have 30 (+0) magic resist, while melee have 30 (+1.25). And 340 is the highest movement speed for ranged champions.

You do not need to copy paste stats from another champion, but looking at a similar champion's stats for guidance is a good idea. The lists where champions are sorted after a specific stat could also be useful so you have an idea where your champion stands in squishiness/tankiness/damage etc.
