Job select cards are generally pretty solid, though there are a couple of stinkers (i.e., Red Mage's Rapier and Sage's Nouliths)

Essentially, if you have a full party with all four of these on the board, you can pay one white, one blue, and one black mana to give the Warrior lifelink, deathtouch, and make him unblockable (deathtouch and unblockable at the same time has no real use, but thats still OP to think about)
