General magicians list:
1) Yunalesca
FFX's original summoner should be able to pack a punch in a contest setting.
2) Tellah
Though he has only appeared in two contests (promptly booted each time) I have a hard time believing he's really less likable than Cid, Palom or Porom.
3) Braska
With Jecht's midcard status firmly confirmed, the mage type character from never-to-be prequel FFX-0 deserves to show what he can do.
4) Ingus
Though FF3 doesn't use set job classes, he is shown as a Red Mage at one point in the intro. I've always had a fondness for red mages, so he gets a nod here.
5) Strago Magus
Ever notice old guys are not very popular in the contest?
