Honestly, the whole 'you only get magic that relates to your talent' thing sort of bothers me.
In my interpretation, everything ponies do has innate magic to it.
Basically all ponies can do magic, except Earth ponies are capable of Earth magic and self-improvement chi sort of thing, pegasi are adept at weather control, and unicorns govern telekinesis.
Assuming you're roleplaying a bareflanked filly, you need to roll Critical Success to acquire your cutie mark. You are allowed to not pick it as your cutie mark (explains the CMC), however, you must decide on it immediately after it happens. The point is, it is simply impossible to even get a Magic cutie mark, much like it's impossible to get a Flight cutie mark - you can't roll to determine if you succeeded at just doing magic.
Besides, Rarity has a gem-finding talent but is regularly using telekinesis, isn't she?
The way I interpret Twi's CM is not just "magic", it's "magic spark". Wild magic sort of thing. She is capable of intensely powerful spells, but they are very mentally exhaustive and can randomly fumble.

I liek to pretend it is an Anti-Tank Gun.
