Knighthood

Static team-wide combat buffs were the white anthem's bread and butter long before keyword-granting enchantments became routine, and this one hands first strike to your whole board for a flat cost with no upkeep, no equip, and no targeting. The design value is entirely in the math it rewrites at the combat step: every creature you control wins ties it would otherwise trade in, and any attack into a board of equal or smaller bodies becomes a clean trade in your favor. Where a combat trick spends a card and a window to do this once, the enchantment pays its rent every turn it survives, which is the trade-off white token and weenie strategies were built to exploit: flood the board cheap, then make each individual body punch above its toughness in every block and attack. The cost is the obvious one. With no creatures down, or with your team tapped out, it sits there doing nothing, and it folds to any enchantment removal without taking a creature down with it, so it asks you to already have a board worth multiplying before it earns its slot. That conditionality is what keeps a permanent, repeatable first-strike anthem from being oppressive: it is a force multiplier, not a standalone threat, and it wants a wide, aggressive shell to mean anything at all.
