Reading the title of another proposed card gave me this idea. This title is really a white sounding name, and something like it could be attached to a white non-basic hoser. Sure, there are plenty of ways to hate non-basics now, but I was thinking of a very white way to so it, while not neccesarily crippling, messes with their plans a bit. As this is an enchantment, might be better to have a noun rather than verb, but I will leave that for you to offer suggestion about.
Impose Order
Enchantment
When ~this~ comes into play, each player chooses a color. All lands controlled by each player lose all abilites and can only be tapped for the chosen color of mana.
I'm not sure on the wording there, my other thought might be a bit simpler:
Enchantment
When ~this~ comes into play, each player chooses a basic land type. All lands controlled by each player become basic lands of the chosen type.
I leave it to the rules sticklers to figure out what might be the best way to put it; my basic idea from a flavor perspective is to limit both mages to picking a color and sticking with it. It's by no means a crippling effect like Blood Moon or B2B, so perhaps the 2W cost is even too much.
Thoughts, suggestions?
