Cave

Cave is a nonbasic land type used for cards that depict deep caves and caverns. It was introduced in The Lost Caverns of Ixalan.
==Description==
Much like Deserts, Caves are utility lands. They don't have a unique mechanical identity but can be referenced by other cards. To differentiate from Deserts, the cards that refer to it scale up rather than use a binary; the fact that a portion of these lands is put in a large set land slot rather than a common in a small set changes the math slightly.
The Lost Caverns of Ixalan featured a cycle of common Caves that exist in the land slot. These Caves enable descending and represent a spell in the late game.

==Caring about Caves==
Several cards from The Lost Caverns of Ixalan interact with Caves. Many also refer to them in the graveyard as well, given the graveyard theming of the set.
==Trivia==
*Cave once was a proposed basic land type that would have been associated with Purple.
*There are currently no plans to errata older cards that are flavored as caves (e.g. <c>Bloodfell Caves</c>, <c>Gemstone Caverns</c>, <c>Cave of Temptation</c>, <c>Caves of Koilos</c>, <c>Cavern of Souls</c>)
