I think that Mage keyword shuld be removed from this card becouse whit it this card is simply too powerfull for a comon card or it shuld be switch to uncomon.
This card is a comon card deals 5 dmg and gives (at least) +50 mage tolkens all that for 7 gems. Whith mage keyword attached to this card it has a potential to raise magick in just one turn.
Already it is much beter and cheper then any uncomon magick raising card (Apprentice,Book of magic,Mentor,Power surge).
Not to mention that mage keyword makes it yet another comon mage card that can be used by the Ice Queen making it even more powerfull.
