Fearless Halberdier

Three power for three mana with nothing else attached: no keyword, no trigger, no upside, and a back end fragile enough to trade down into most of the creatures it swings at. Designs like this exist as a deliberate floor. When a set needs a common-rarity body to round out an aggressive curve and fill the gaps the more interesting cards leave open, this is the slot it occupies. The two toughness is doing quiet work here, keeping the rate honest: bump that to three and a textless beater would crowd out the cards asked to earn their keywords, so the aggressive front end is balanced by a body that dies to most of what blocks it. Vanilla creatures are easy to dismiss, but they are part of how a designer keeps a set's power band coherent, marking the line below which a card has to justify its extra words. This Human Warrior carries no story past that job: a clean attack step and nothing to remember it by, which is exactly the point.
