Swordsworn Cavalier

A 3/1 for two is a body built to trade up and die fast, the kind of aggressive statline that lives or dies on first strike, and this one earns the keyword only when the Knight deck is doing what it wants: flooding the board a body at a time. The conditional is narrower than the usual "as long as you control another Knight" boilerplate. It cares about a Knight entering this turn, not merely being present, which means the first strike is a reward for developing rather than a permanent fixture. A Knight that came down last turn does nothing; a token or a fresh recruit deployed alongside it flips the switch. That timing detail turns the card into an incentive to keep the curve moving and the attacks pressing, since the turn you go wide is the turn the 3/1 becomes a genuine problem in combat, punching through blockers a fragile toughness would otherwise never survive. Left alone with no reinforcement, it is a vanilla beater with a glass jaw, which is precisely the tension the design wants: the payoff is only ever one deployment away, and the deck that can reliably produce that deployment turns a mediocre rate into a tempo weapon.
