Retreat to Kazanduutility$0.31It has a landfall life-gain mode that rewards every land drop, giving you repeated incremental life in a similar way.
Sunbondutility$0.52This enchantment turns life gain into board growth and also rewards repeated life-gain triggers, making it a good companion to landfall lifegain decks.
Baloth NullutilityBudget$0.05While it doesn't trigger from landfall, it is a green creature that stabilizes life totals and supports graveyard-based midrange decks like Grazing Gladehart often does.
Jaddi Offshootutility$0.19This is the closest direct analogue: a cheap green creature with landfall that repeatedly gains life whenever lands enter the battlefield.
Courser of Kruphixutility$2.83It gives continuous value off land drops, helps stabilize life total, and plays in the same green ramp/gain-life shell.
Canopy Vistautility$2.80As a land with a lifegain-related type synergy and green identity, it fits in green life-gain/ramp decks that want land-based value.
Amulet of Vigorutility$51.28Not a life-gain card itself, but it strongly supports land-drop strategies by making extra land value immediate, which pairs well with landfall payoffs.
Rampaging Balothsutility$0.54Another green landfall creature that turns every land drop into a meaningful payoff; it is a higher-impact sibling to Grazing Gladehart in landfall decks.
