Well, not to brag or anything, but I happen to be particularly magically talented, even by the standards of unicorns. I don't remember if I ever told you this or not, but Princess Celestia actually made me her personal pupil.

... Looking back on it, she probably did that to make sure I didn't accidentally cause too much trouble.

[Giant rampaging dragons would not be good for anyone.]

Regardless, only a few of my spells can rival what you're doing, and most of them tire me out quite a bit to use. Though, that might be because you're a lot more specialized than I am.
