Fast land

The fast lands or scar lands are a double cycle of taplands. The allied color lands were featured in Scars of Mirrodin. The enemy colored cycle was later introduced in Kaladesh.

Description
These lands produce two colors of mana and enter the battlefield tapped unless you control two or fewer other lands.

Wizards of the Coast originally only referred to this cycle as scar lands, after the first set they appeared in, though several nicknames were quickly proposed by the Magic community. WotC finally adopted fast lands as the preferred name.
