A-Thran Portal
A land that names its color on the way in, and pays for the privilege one point of life at a time. Lands that tap for life are an old idea: the painlands charged you a point for colored mana, the shocklands let you pay two to skip the tapped clause, and City of Brass and Mana Confluence bled you for any color at all. This one narrows that tradition to whichever basic type you name as it enters, so it produces exactly one color rather than a spread, but keeps the life tax on every activation. That turns the fixing question from "can I make the color" into "how many times can I afford to make it." The Gate subtype is the quiet structural payoff, wiring the land into the small web of cards that reward Gates directly, so it does work beyond its mana. What keeps the trade honest is that the cost scales with use rather than entry: it comes down untapped and typed for whatever you need, generous on the turn you play it, then charges you every subsequent tap. That profile favors decks that want fixing early and expect to close before the bleed compounds, and it punishes grinding games where every point is a resource. The "A-" prefix marks it as a digital-only Alchemy rebalance of the paper Thran Portal, tuned for that environment; the underlying trade (name your type, bleed for it) is unchanged.
