--I meant to go back and remove Character; I think it was linking at some point or something, but I realized it isn't now

--If you think about how often it will be used in conversation, Shadow is almost always going to be referring to the Shadow alignment/player, both of which are linked enough to be lumped together under alignment. We don't need a page on "opponent" (which is all "Shadow Player" would boil down to) any more than we need a page on "card", it's an instantly recognized part of the game. "Shadow Phase" is always going to be used in that order, too, so I think it will take care of itself.
--Twilight is indeed a keyword, but I think in this case, what with the sheer number of times that "twilight pool" and "twilight tokens" are going to be referred to (especially in comparison to the relatively obscure Twilight Nazgul), it needs an exception to the default autolinking behavior.
And I think I got sniped while editing, but I also added "side" and "Free Peoples" to my list, for comparable reasons to the above.
