Deserted token:
Type: Enchantment Token
Enchanted land is every basic land type and loses all other abilities.

The purpose of this card and token would be to provide more options for fair 'land hate' (specifically against nonbasic lands) without resorting to land destruction/exile or mass land denial (like Magus of the Moon). For the land card's owner, it provides the advantage of disabling the abilities of an opponents' land (like Nykthos, Shrine to Nyx), providing generic mana over the course of a game, or providing colored mana at a cost. For the opponent, it can be reacted to by countering the 'Enter-The-Battlefield' trigger, removing the enchantment, or taking advantage of the land that is now all basic land types. The idea is that the card, while universally playable, wouldn't be an auto-include in all decks since there are drawbacks that can accelerate your opponent's game plan and delay your own. The card and token names can be changed to whatever is appropriate.
