Death to Final Fantasy. The cutesy violence of the poisonous franchise will spoil the beauty of the brikshed. I say, get something more original, think of some new ideas, and get someone to make some original art for you. Legos belong in that explody frame, not characters from popular video games. Magicians are a staple in tabletop gaming, but you can't go yanking ideas from other games.
Other than that, it's a decent card. It isn't funny like most cards now, but I think you should keep up the good work. You'll figure it all out eventually. Also, one last bit of advice, give characters quirks. For instance, the ninja is an egotist and the sniper is paranoid. Make something up that makes the mage balanced.
Hey, welcome to Brikwars.
