Sigiled Paladin

First strike and exalted are the same idea told twice, and stacking them is the whole point. Exalted rewards the lone attacker; first strike makes that attacker survive the swing it provokes. A 2/2 that becomes a 3/3 first striker when it goes in alone trades up against most early bodies and refuses to die to the blocks an unboosted creature would lose. The keyword push sits at the heart of the exalted mechanic's design: a board of these does not gang up, it elects a champion each turn and pours the bonuses into it, so first strike scales with every other exalted source on your side rather than wasting on a creature that already wins combat. The tension the design lives inside is that exalted wants you to attack with one creature while a developed board wants to swarm; pairing it with first strike narrows that gap by making the solo attacker genuinely dangerous instead of merely buffed. It is a deliberately small, additive piece, built so that two copies of the same effect compound into something the rate alone does not advertise.
