Knight of New Alara

The math here is the whole reward and the whole trap. The anthem scales with color count, not creature count, so a board of gold two-color creatures each gets +2/+2 while three-color creatures each get +3/+3. That sets up a deckbuilding axis most lords never touch: this card pays you for committing to multicolor density rather than to a single tribe, and it pays disproportionately the deeper into the color pie your other creatures reach. What keeps it honest is its own body. As a 2/2, it buffs every multicolored creature you control except itself, so it offers no anthem protection for the creature most likely to draw removal first. Knock it off the board and the whole team shrinks at once, which means the value lives in winning the turn it stabilizes a wide gold board rather than grinding behind it. Among lords that reward color identity over creature type, this one pushes hardest toward three colors and beyond, where the per-color multiplier turns ordinary midrange bodies into genuine threats.
