These lands should be joined by legendary pure versions of basic islands, plains, and forests, and legendary impure versions of basic islands, swamps, and mountains, as well as the legendary white and black lands I listed before. (Blue gets the worst legendary lands because it has the option of pure/impure just in blue.) So each color has 2 legendary lands now in addition to basics.
