Nonbasic lands are Mountains.
Watch Out
Layer interactions with land abilitiesCommon Misplay
Blood Moon operates in Layer 4 (type-changing), making nonbasic lands Mountains. They lose all printed abilities in Layer 6. Lands that would ETB tapped from a replacement effect (like shocklands) still ETB tapped — the replacement applies before Blood Moon's continuous effect.
CR 613.1dBasic lands are completely unaffectedWatch Out
Blood Moon only affects nonbasic lands. Basic lands keep all abilities. Fetch lands become Mountains and can't sacrifice themselves.
