Sea Gate Wreckage

A colorless land that turns the deck's worst position into a refuel button: the empty-handed turn that signals a flagging aggro deck is exactly the condition this draws from. The hellbent restriction pays for everything else. Card advantage on a land would be free value otherwise, so the design ties it to a state most decks try to avoid: zero cards in hand. That makes the engine self-limiting in slower decks (you rarely empty out) while paying handsomely in decks built to dump their grip by turn three or four, the kind that would otherwise flood out and lose the long game. The activation is steep enough ( per card) that it never spirals; it drips out gas incrementally, restoring the reach a fast deck runs dry of rather than burying an opponent under a fresh hand. Structurally it does the same work as the old "spend your resources, then refill" engines, but priced onto a land and gated behind an emptied hand rather than a life total or a permanent you have to keep alive. The colorless mana symbol in the activation is the quiet tax that keeps it out of every aggressive shell: you need a deck producing reliably, which historically meant the artifact-leaning and Eldrazi-adjacent builds where empty hands and colorless sources naturally coexist.
