I chose to post the lands first to show how the dying sun has leached heat from the world. This cycle of Rare lands mirror the Rare landfs from M10/M11/M12 but require Snow versions of the requisite basic lands to ETB untapped. As there are Snow-Covered Basic lands in the set as well, this isn't an issue and makes them strictly worse than the aforementioned core set rare lands. If I expand this to a second set, it will incorporate a cycle of non-basic snow lands with the basic land types (so a Snow Land - Plains, etc) to further help.
