Abundant Harvest

The problem this solves is the oldest one in green: the color that ramps and draws cards has no cheap, unconditional way to filter its draws, and green decks flood on lands or starve for them depending on the coin flip of the top of the library. This resolves the flood-or-starve tension with a single decision made at cast: name the resource you are short on, and the card digs until it finds one. It is functionally a one-mana cantrip that always hits, but the choice is the whole engine. In a deck that wants to keep hitting land drops, you name land and treat it as a smoothing tool; when your curve is topped out and you need action, you name nonland and it becomes selection that skips the dead draws. The bottoming clause is what pays for the flexibility: you do not thin the library so much as tuck the passed-over cards away, and everything you passed over goes to the bottom rather than into your hand, so the card never overdelivers. Green rarely gets to touch its own draw step at this rate, and the design treats that scarcity as the price: you get the fixing and the selection, but only one card, and only the kind you asked for. It is the rare piece of green card-selection that reads as a deliberate concession rather than a splashy one.
