If it really scares you that muck, get working on your SCIENCE! It's the only thing that can surpass it.
Twilight:...I feel really conflicted here.
On a side note, I don't like the whole 'magic deus ex machina' solves everything. It's like watching a commercial.

Rarity: Terrifying? Moi? Applejack: Yeah! Ah mean, with one quick spell, y'all could- Rarity: *ZAP* Applejack: ... y'all could... could... Rarity: I'm sorry, dear, what was that?

Oh, nerfing happens all the time on the show. Remember when Twilight was being chased by the Hydra and forgot she could teleport? Or the many, many times when being able to levitate stuff as heavy as a bear the size of a house would be useful?
........yeah that would not work. it is gem finding.
actually it seems to me that in equestria gems are, in fact, solidified magical energy. think about it. the most powerful magical artifacts of equestria have hve gems or are gems, like the heart and the elements. the most powerful Thing in equestria appears to be a tree of living crystal even.
