Land Grant

Storm and combo decks adopted this for a reason that has nothing to do with green ramp: with no land cards in hand, the spell costs zero mana, swapping a Forest from your library into your hand for the price of revealing your grip. That clause turns a humble fixing sorcery into a free library-thinning effect, which is exactly what a deck running so few lands it rarely holds one wants. The resource being spent is information, not mana: you show your opponent you are landlight, and in exchange you keep your colored mana free for the kill. The condition is honest. You only get the free cast when your hand has no lands, so the card sculpts your draw and parks a card in hand rather than ramping a permanent onto the battlefield. Two details make it more than a basic tutor. It fetches any Forest card, not just a basic, so anything carrying the Forest type qualifies: dual lands and utility lands with the subtype are all legal targets. And because the free version trims one land from your deck while costing nothing but the card slot, it functions as quiet deck-smoothing in builds that never wanted the Forest in play to begin with. The design sits among the first cards to source their cost from somewhere other than the mana pool, paying in the contents of your hand rather than your lands.
