Sulfurous Mire

The taplands have always been the honest fixing: no life payment, no fetch chain, no basic-type requirement, just two colors for the cost of a turn's tempo. What sets this iteration apart from the older Rakdos entry-tapped duals is a single supertype word that costs nothing to include and pays out for anything that reads it. Being a snow permanent means every mana it produces is snow mana, and every land drop feeds the count that snow payoffs care about. That turns a card whose function is otherwise settled (fix black and red, come in tapped) into a load-bearing piece for a deck built around snow synergies rather than raw fixing. The two basic land types stacked onto it (Swamp and Mountain) matter too, letting it be found by anything that fetches a basic land type and letting it dodge nonbasic hate that keys off missing types. The tempo hit is the whole cost of admission, and it is the same cost the untyped entry-tapped duals have always asked. The difference is what the land is on top of paying that price: a fetchable, dual-typed source that quietly adds to your snow count every time it touches the battlefield.
