Shifting Woodland
A green source that pays rent up front (it enters tapped without a Forest to lean on) and then, once the graveyard is stocked, stops behaving like a land at all. The delirium clause turns it into a manland with no fixed body: for four mana it becomes a copy of any permanent card sitting in your graveyard until end of turn. Ordinary creature-lands lock into a single predictable shape; here the shape is whatever you have discarded, milled, or sacrificed: a fatty finisher to swing with, a value-engine enchantment, an artifact you would rather have back on the battlefield. The one shape it cannot usefully take is a planeswalker; a copy made this way does not enter the battlefield, so it gains no starting loyalty and is put into the graveyard as a state-based action the moment it exists. The copy clause is limited to permanent cards, so it also sidesteps the awkwardness of impersonating an instant or sorcery, and the end-of-turn window means each activation is a one-shot: you pay again every turn you want the body back. The delirium gate is the cost of all this flexibility, forcing you to assemble four card types before the ability comes online rather than handing over a free late-game bomb. Where a creature-land promises one repeatable threat, this land instead asks you to build a graveyard worth impersonating, then rents its identity from whatever you buried.
