What was I thinking? Why did that matter? Blue has too many overall cards and I'd rather have bigger creatures in Green and Red.
It's difficult to imagine a world in which there's any real sense of balance among colors in the cube, but it's worth trying. Again though, does it matter? Maybe there's some sub-game going on where if you cast three spells of the same color in a row then you get a little bonus. Making a note of it here.
Also I'm wondering if Gleemax is no fun, so I'm getting rid of it.
