Smoldering Crater

Manabases have always wrestled with two opposite hungers: a deck wants colored sources early and gas late, and one nonbasic could not historically be both. This kind of dual-purpose land splits the difference by letting the card behave as a spell on the turns the land itself is dead weight. Stuck with too many lands and a full board, you pitch it to draw a replacement; need a tapped red source instead, and it sits in the manabase like any other tapland. The cost of that escape hatch is paid the moment it touches the battlefield: entering tapped is a tempo tax that prevents the cycler from ever being strictly superior to a basic. That tempo penalty is the lever Wizards has reached for on every cycling-land variant since, including the dual-color versions that arrived much later. This is the red entry in the original cycle, and the design shows in its plainest form, untwisted by additional text. It is the cleanest illustration of the underlying idea: a land that anticipates being unwanted and builds the door out into its own rules box.
