Herald of Dromoka
Vigilance is the keyword white aggro almost never gets to keep: the whole point of a one- or two-drop is to attack, and attacking usually means tapping out the board on the turn you most want a blocker back. This anthem resolves that tension by handing the keyword to the entire Warrior tribe rather than to a single attacker, which turns a wide go-wide board into one that can swing for the kill and still wall the crackback. The 2/2 statline is incidental; the value lives in the static, and it scales with every Warrior you stick afterward. It grants no power or toughness, only confers the keyword, so it asks you to already have a Warrior board worth keeping untapped rather than a single threat worth protecting. That places it a tier below the standard tribal lord (which usually grows the team) and squarely in the support slot, a redundancy piece that makes an aggressive curve harder to race. Warriors as a creature type span enough sets that this kind of tribal connective tissue has a home wherever the deck wants to commit bodies and still hold the ground it took.
