Spear of Heliod

White's anthem effects have always lived in a tense bargain: a board-wide buff is worth most when you have the widest board, which is exactly when you least want to spend a card slot on something that does nothing by itself. This one answers the second half of that bargain with a stapled-on removal valve. The static +1/+1 is the familiar Glorious Anthem rate, but the activated ability turns the enchantment from a pure force-multiplier into a piece of attrition: hold up the mana, take a hit, and remove the attacker on your terms. The targeting clause is the discipline behind the whole design, since it only points at creatures that have already dealt you damage this turn. It punishes the aggressor rather than preempting them, and it cannot answer a blocker or a freshly cast threat sitting back. That restriction reorients the card around defense and racing math: an opponent attacking into a buffed board now risks losing the attacker outright, which warps the combat step in a way a plain anthem never could. The legendary tag is the other guardrail, capping a recurring removal engine at one copy in play. It is one of the rare anthems that earns its keep even when the board is empty, because the threat of the activation does work before a single mana is spent.
