For example, I select one particular set under "sets". Then I go to filters, and all the color settings seem to have three options: a full box, a check mark, and empty. If I unmark all of the colors but, say, green, all that shows up are spells that have ONLY green mana in their casting cost. But if I add colorless to it, it shows all green spells in that set, AS WELL AS artifact and lands. This is really freaking annoying! Whatever happened to just selecting one color and seeing all the spells of that color?
