I believe this is the reference you're looking for:
 * Spike: Twenty-five, Twilight. Twenty-five different kinds of tricks and counting. I thought unicorns were only supposed to have a little magic that matches their special talents!
 * Twilight Sparkle: True, for ponies whose talents are for things like cooking or singing or math. But what if a unicorn's special talent is magic?

Sweetie Belle also has the benefit of having been tutored by at least one former unicorn who can teleport. If Trixie can learn how to do it, it can't be that difficult.
