Elite Archers

The pinger that only fires in combat, and that restriction is the whole point. A repeatable three-damage shot is normally the kind of effect Wizards keeps to small, costly bursts or locks behind colors that don't get to keep their creatures alive; here white gets it on a body, but only against creatures already committed to an attack or block. That clause makes the card a defensive anchor rather than a board-control engine: it can't pick off a mana dork on an early turn or snipe a planeswalker, but it punishes anyone who tries to push damage through it, and three is a high enough number to outrange most of the era's combat-relevant bodies. The tap cost is more flexible than it first looks, since the archers can be declared as a blocker and then tapped to fire at the creature they're already facing down, killing an attacker before combat damage and surviving the exchange. It's a clean expression of an old white design instinct: reward the player who sits back and defends, but make sure the reward never becomes proactive removal. The six-mana price is the final governor, keeping a repeatable damage source out of the early turns where it would simply erase aggression before it started.
