Nonbasic land
Nonbasic is a card, usually a land, that doesn't have the basic supertype. As per Magic rules, only 4 of each nonbasic land can be in a deck at any one time. Basic lands do not have this restriction.[1] Nonbasic lands often depict notable locations from the relevant set's style guide. [2]
Rules
From the Comprehensive Rules (June 7, 2024—Modern Horizons 3)
- 205.4c Any land with the supertype “basic” is a basic land. Any land that doesn’t have this supertype is a nonbasic land, even if it has a basic land type.
Cards printed in sets prior to the Eighth Edition core set didn’t use the word “basic” to indicate a basic land. Cards from those sets with the following names are basic lands and have received errata in the Oracle card reference accordingly: Forest, Island, Mountain, Plains, Swamp, Snow-Covered Forest, Snow-Covered Island, Snow-Covered Mountain, Snow-Covered Plains, and Snow-Covered Swamp.
Note that a nonbasic land may have a basic land type (Plains, Island, etc).
