Soltari Trooper

The attack trigger is the whole pitch: a 1/1 that becomes a 2/2 the instant it commits to the red zone, then shrinks back to its fragile printed body when the turn ends. That swing-only bonus turns the creature into a metronome of incremental damage rather than a stat you can sit on, and the evasion built into the soltari clan is what makes the math hold up. A creature that the opponent's ground blockers cannot touch deals its damage regardless of what they have deployed, so the two points connect with a reliability a same-sized groundpounder never gets. The discipline cuts both ways. Because the boost lasts only until end of turn, a Trooper that stays home contributes nothing, and one that swings reverts to a 1/1 vulnerable to anything that does not require getting through the front line: a ping, a minus-one toughness effect, a single point of reach damage. The card is tuned to reward racing and to punish hesitation, asking you to keep it swinging or accept that it does nothing at rest. That tension, between a clock you cannot block and a body that falls over to almost anything off-combat, is the entire design folded into a two-mana attacker.
