Cyclopean Tomb (30A-533) is an artifact from the 30th Anniversary Edition reprint set. It can tap for {2} and put mire counters on non-Swamp lands, turning them into Swamps while they have those counters; the activation is restricted to your upkeep. If it dies, it creates a delayed triggered ability that lets you remove mire counters from lands during each of your upkeeps for the rest of the game.
