Land type

A land type is any subtype used for the further classification of land cards.
Unlike creature types, land types don't have to appear on all lands. Instead they are only introduced for mechanical purposes.
==Rules==
==Basic land types==
The most common lands are the five colored basic lands. Each have the supertype "basic" (meaning there is no limit to how many cards of that name you can have in a constructed deck), a subtype matching its name, and a single activated ability allowing you to tap it to generate one colored mana. 
These basic land types and the mana they generate are: 
*Plains — white
*Island — blue
*Swamp — black
*Mountain — red
*Forest — green
When an effect specifically refers to "basic land type," it is referring to any or all of these five subtypes.
Ordinarily, changing a card's subtype does not automatically change its abilities, but the basic land types are an exception. If a land gains a basic land type, it also gains the ability to tap for the appropriate color of mana (and loses all other abilities, unless the type-changing effect allows it to keep its original types.)
==Nonbasic land types==
There are some land types associated with nonbasic lands:
*Cave associated with the core of Ixalan.
*Desert the first nonbasic land type introduced.
*Gate associated with the guilds of Ravnica.
*Lair associated with the Primeval Dragons.
*Locus associated with Mirrodin and has magnifying effects.
*Sphere associated with the Spheres of New Phyrexia.
*Urza's originally featured on a set of three lands that combine for seven colorless mana. Additional lands with the type have been added since.
**Mine
**Power-Plant 
**Tower
==Playtest land types==
There are some land types associated with playtest cards. These types are nonbasic:
*Omenpath associated with vanishing.
*Town representative of urban areas and small villages.
*Ulamog's associated with the Eldrazi titan of the same name. 
==Trivia==
*Rangeling is an Acorn keyword that gives a land every land type, including the basic land types.
** is the first Eternal-legal card to have all non-basic land types.
** also grants all land types to lands. This time through an everything counter.
