Snow Land — Swamp Forest
Snow is a supertype with no inherent functionality. Instead, it serves as an identifying characteristic of permanents and spells, and is closely tied to snow activation costs and mana costs. Snow is a replacement for the supertype "Snow-Covered". Lands represent locations under the player's control, most of which have mana abilities. Forest is one of the five basic land types and provides green mana, which is required to cast green spells. Swamp is one of the five basic land types and provides black mana, which is required to cast black spells.
