Wasteful Harvest

Green has always dug through its own library: Mulch, Satyr Wayfinder, and a long line of Regrowth effects put self-mill and graveyard recursion squarely in the color's pie. This one shares the family's shape (churn the top of the deck, keep one thing, let the rest pile up in the yard) but rearranges the timing and the target. The five cards that hit the graveyard are not the cost; they are the search space, and the pull-back clause reaches only permanents, so this stops short of a universal Impulse. In a deck built around lands, artifacts, and creatures, the grab is a near-certain hit; in a spell-heavy shell it can whiff on the retrieval entirely. That is the honest tension the effect runs on. Where a card-selection spell like Impulse tucks the leftovers onto the bottom of the library, here the four unchosen cards stay in the graveyard, so a miss on the pull-back is never truly wasted in a deck that wants a stocked yard: reanimation targets, delve fuel, and lands for recursion all end up exactly where the deck can use them. And unlike most green self-mill, which arrives stapled to a sorcery-speed body, this fits into an instant, so it can be held to an end step to shape the following turn without spending your main phase or tipping your hand.
