The trigger keys on tapping, not attacking, and everything the card is worth flows from that choice. A creature that pays out only when it attacks gives you one dividend per combat, and only on turns you're the aggressor; keying off the tap itself means the two life fires whenever the body is put to work, whether that's crewing a vehicle, convoking a spell, paying a tap-cost activation, or being pulled sideways by an opponent's effect. Vigilance would quietly defeat it, since a creature that never taps never gains, so you want this one spent: tapped early, tapped often, tapped for something other than the red zone. That reframes a plain 2/2 into a small, repeatable life engine that rewards decks already built to sink their creatures into tap costs. Repeatable lifegain has long clustered on a few axes: Soul Warden and its kin trigger on other creatures entering, other designs gain on combat damage. Tap-triggered payoff sits in a quieter lineage; it's indifferent to what the creature is worth in combat, caring only that you keep asking it to do jobs. Standing alone it drips value slowly. Surrounded by cheap tap outlets it turns each activation into a two-life dividend, and the ceiling climbs with every extra tap you can wring out of a single turn.
