Crusade

The original tribal lord, printed before "lord" was a design pattern Wizards consciously named. The construction is the bluntest possible version of the idea: a static anthem keyed to a color rather than a creature type, costing two white mana, with no body attached and no clause to soften the symmetry. Every white creature on the battlefield gets the bonus, including an opponent's, a quirk the card simply accepted in an era when mirror matches and shared-color games were assumed to be part of the texture. The lineage that descends from it is enormous: Honor of the Pure kept the same mana value while easing the color requirement to a single white pip, narrowing the anthem to your own creatures in the process; Glorious Anthem swapped to a fully generic anthem; and every creature-type lord from Lord of Atlantis forward inherited the +1/+1 anthem shape while attaching it to a body. Crusade itself was eventually retired from reprint rotation for flavor reasons rather than power ones, the religious-war framing becoming untenable for a game that wanted broader cultural reach. What it leaves behind is the template: the anthem as a deckbuilding tax that pays itself back once the board has three relevant creatures on it, a math problem every white weenie deck since has been built to solve.
