Sulfurous Mire
Snow Land — Swamp Mountain
"In my youth, we used to best each other at hopping rabbit-fast between the lava spouts, the burning tar spattering our legs." —Iskene, Kannah storyteller
Rulings (5)
Snow is a supertype, not a card type. It has no rules meaning or function by itself, but spells and abilities may refer to it.
Some cards have additional effects for each snow mana spent to cast them. You can cast these spells even if you don't spend any snow mana to cast them; their additional effects simply won't do anything.
The Kaldheim set doesn't have any cards with mana costs that include snow mana , but some previous sets do. If an effect says such a spell costs 1 generic mana less to cast, that reduction doesn't apply to any snow mana costs. This is also true for activated abilities that include snow mana in their activation costs and effects that reduce those costs.
