Guardian Projectcard_draw$19.96A premier green card-advantage engine for creature-heavy decks, drawing cards off nontoken creatures entering the battlefield. It fills the same role of rewarding you for playing lots of creatures.
The Great Hengecard_draw$57.37A powerful green value engine that repeatedly draws cards as your creatures enter and also ramps and stabilizes your board. It serves the same long-game draw role in creature decks, with much higher ceiling.
Soul of the Harvestcard_drawBudget$1.27Like Beast Whisperer, it rewards you for casting or resolving creatures by drawing cards off creature ETBs. It is a creature-based source of continuous advantage in green decks.
Primordial Sagecard_drawBudget$0.62This is one of the closest functional analogs, drawing a card whenever you cast a creature spell. It is essentially the same role at a higher mana cost and with a different body.
Garruk's Uprisingcard_drawBudget$0.83A budget-friendly green value enchantment for creature decks, drawing cards when big creatures enter and granting trample. It is less universal than Beast Whisperer but still serves as a repeatable draw engine.
Elemental Bondcard_draw$7.19A cheaper repeatable draw engine for creature-heavy green decks, drawing when larger creatures enter. It overlaps in role by turning creature deployment into card advantage.
Beastmaster Ascensionfinisher$3.74Not a draw engine, but often paired with creature-swarm strategies to convert a stream of creatures into a win condition. If you want a creature-scaling payoff in green, it fills a similar deck role alongside card-advantage engines.
Setessan Championcard_draw$8.94A green card-advantage creature that draws cards when enchantments enter, making it a similar engine in decks built around a permanent type theme. It is not creature-specific, but it occupies the same 'repeatable green draw creature' slot.
