The average unicorn simply doesn't have access to spells like that. A typical unicorn has telekinesis, and a little magic related to their special talent.
I think Rarity is a much better example of a more typical Unicorn. For example, the extent of rarity's magic is telekinesis, and detecting gems. For one, Rarity's telekinesis is far stronger than a piddly little Mage Hand. She can juggle five dressmaker's dummies at once. For two, her other magical abilities are very limited and specific, to the point that they might as well be ribbons.
I think it would be better if the race focused more on telekinesis than on a set of spells once per day, because telekinesis is a far more universal trait of unicorns.
