Intrepid Adversary
Obviously, being a human creature, Intrepid Adversary fits right into humans deck. But his ability is not limited to humans only and he can become a good additional lord to any other tribal deck.
Remember that it also buffs itself, which is unusual for lords, where you get a 4/2 creature for 4 mana. Since this is an ETB effect, it can be doubled. Most importantly it's not legendary, which allows you to play several copies at a time.
