Pothole Mole

Mill has spent most of its life as an opponent-facing clock, a slow attempt to deck someone out. Green has quietly repurposed it as self-selection: fill your own graveyard, then reach in and take back the piece you want. This creature is that idea compressed into a single body. The three cards it puts into your yard are not the payoff; the land you return is. It turns milling from a resource loss into a filtering step, digging three deep for something specific while the rest of the pile becomes fodder for whatever recursion or delve costs your deck already wants filled. The land clause matters more than it reads: it can smooth a land-light draw into an extra play, and if the mill happens to bury a fetchable enters-the-battlefield land or a utility land you had already run out of, the ceiling climbs without ever asking you to do anything but cast a fair-costed creature. The return is optional, which is the wrinkle that keeps it clean: on a flooded board you simply take the mill and skip the return, so the card never punishes you for having enough lands already. A green three-drop that fixes mana, feeds a graveyard, and demands no setup is doing three jobs at a rate that would only support one of them alone, and the reason it works is that none of those jobs asks the card to be more than it is.
