Most powerful character in tactics

I just read the thread about everybodies favorite final fantasy games and i decided that it would be interesting to see what everyone thought the ideal character in final fantasy tactics would be.
personally i've found my claculator/black mage to be the strongest and most influential character in any battle. He is master calculator and a master black mage, he uses autopotion, magicattackup, and move+2(he doesn't have teleport yet). He carries the items that will help boost his magic attack the most (magic gaunlet etc.) and he is currently only lv 60, but i'm working on em
Oh, and he is a black mage with math skill as his secondary because 1)black mage has highest default magic attack of all classes 2) calculators are stupidly slow.
