Chieftain en-Dal

First strike is normally a defender's keyword, the answer to "you block, you kill before you die." This Knight inverts it into an offensive lever: swing it in and the whole attacking team gains first strike for the turn, which turns a wide white board from a stack of mutually-traded bodies into a force that wins every combat exchange outright. What balances the effect is the attack trigger itself: the buff only fires when this creature commits to combat, so a defending opponent never borrows the keyword on their own swing. And because the trigger resolves during the declare attackers step, before blockers are chosen, the buff locks in across the team for the turn; chump-blocking the Chieftain afterward does nothing to claw it back. The design reads like a weenie-anthem effect bolted onto an attack step, the same plan Glorious Anthem pursues through a static buff, except here the payoff is a combat-math rewrite rather than a power-toughness bump. White Weenie has always wanted to alpha-strike into a parity board and come out ahead; first strike across the team is precisely the tool that makes the alpha strike asymmetrical, since the blocker's creatures deal damage a beat too late to matter. The 2/2 body contributes nothing on its own, which is the price of an effect that scales with how many other attackers are already on the table.
