The magical feats of a prodigy whose special talent is literally magic =/= the average unicorn. Can most unicorns even teleport? They seem mostly limited to telekinesis and maybe a spell or two related to their cutiemark. Granted telekinesis is extremely useful for a thumbless species, but I don't think the gap between tribes is as wide as you make it out, and wouldn't discount the perks of Earth Ponies and Pegasi that casually.
