Basic

Basic is a supertype found on the basic lands Plains, Island, Swamp, Mountain, and Forest.

A card with the Basic supertype has special rules associated with it: it is not bound by the four card maximum rule that other cards are restricted to in constructed decks.

The word Basic was first seen on the basic lands in Eighth Edition in order to help players understand what exactly the term meant, as the basic land types (Plains, Island, Swamp, Mountain and Forest) were not always associated with basic lands (such as the original dual lands printed in the Beta set).
