Vernal Fen

The dual-typed subtype line is doing precise work here, but not the work a careless read assumes. Because this land is a Swamp and a Forest without the Basic supertype, it lives in a narrow gap between the two fetch categories: Nature's Lore and Farseek find it, since they search by subtype and do not care whether the land is basic, while anything hunting a genuine Basic (Rampant Growth chief among them) passes it by. That distinction is the whole design, and it cuts the other way too. The land wants you to control two or more basics to enter untapped, and it cannot help satisfy that clause for itself or for the next tapland behind it, because it is not one of the basics being counted. So the conditional does real balancing: a zero-cost dual that always entered untapped would be too clean, a pure tapland too slow, and this splits the difference by rewarding a manabase that stays honest about its true basic count rather than loading up on nonbasics. The result is a fixer that gets better the more conventional your lands are, which inverts the usual instinct to cram in exotic duals. It is a workmanlike black-green fixer of the kind that never headlines a deck but keeps the early curve on schedule, and the untapped condition is forgiving enough to click on reliably once a couple of basics have hit the table.
