Imprisoned in the Moon

The permanent will keep any supertypes it previously had. Notably, if Imprisoned in the Moon is enchanting a legendary permanent, that permanent will continue to be legendary.

If you remove Imprisoned in the Moon from a planeswalker after tapping it for mana, you can still activate a loyalty ability of that planeswalker even though it's tapped.

If the enchanted permanent is a land and has land types, it retains those types even though it loses any intrinsic mana abilities associated with them. For example, a Plains enchanted by Imprisoned in the Moon is still a Plains, but it can't tap for white mana , only for colorless mana .
