Most repeatable tappers commit to one face of the same effect: tap the enemy blocker every turn and you have an attack, tap the enemy attacker and you have a wall. Letting a single activation do either turns the ability into a dial you can aim at your own side too, which is where the design gets interesting. Untapping does nothing for a creature already standing ready, so its job is to refresh a creature that has spent its own tap ability, give a freshly attacked creature pseudo-vigilance so it can block back, or free up something you tapped to pay a cost. What this wants alongside it, then, is a board where tapping means something worth resetting. The two-mana-plus-tap price keeps the lever in check: one creature per turn, never the board-locking grind a free tapper threatens, and it spends its own tap each time it works. The 1/2 body plants it firmly in support; it reads less as a creature you cast for combat and more as an attachment that makes a tap-matters strategy hum.
