Icatian JavelineersutilityBudget$0.02A one-mana white creature with a simple activated utility ability, giving you board presence and repeatable value in the same low-cost support slot.
Healer's Hawklifegain$0.09Another efficient white one-drop that supports lifegain strategies, though it gains life through lifelink combat instead of an activated ability.
Ajani's Pridematelifegain$0.20A classic white lifegain payoff creature in the same color, useful if Soulmender is part of a lifegain engine.
Sunbondlifegain$0.52A low-cost white lifegain enabler/payoff that scales with repeated life gain, fitting the same archetype Soulmender supports.
Soul Wardenlifegain$2.76The closest functional equivalent, gaining life repeatedly from creature entries instead of tapping, and often stronger in lifegain decks.
Soul's Attendantlifegain$9.06Very similar to Soul Warden, providing repeatable life gain as creatures enter the battlefield rather than an activated tap ability.
Auriok Championlifegain$11.22A premium lifegain creature with protection and a repeatable life-gain trigger, serving a similar role in white lifegain shells.
Dawntreader Elkutility$0.13A cheap creature with a tap-and-sacrifice utility activation, similar in the sense of being a small body that converts into incremental advantage.
