Herald of the Fair

The 3/2 body is the tell: the enters-the-battlefield pump is paid for with a fragile back end rather than a steeper cost, which is exactly how this tier of common creature is meant to be balanced. The buff is single-use and locked to a creature you already control, but the wording lets it target itself, so even on an empty board it lands as a 4/3 until end of turn. That self-targeting clause rescues the card from ever being dead weight; the ceiling is a go-wide white aggro shell where the pump pushes a second creature out of burn range or nudges a stalled board into lethal. Strip away the trigger and you have a vanilla 3/2, with all the value front-loaded into the turn it arrives. It fills the three-slot in a token-flavored or tribal aggro plan and asks for nothing more than a body to amplify, including its own.
