There’s only 20 blue creatures in the cube, which sounds roughly right. Blue is supposed to be a spell color (in fact, the most spell intensive), so this is good. The curve is little lacking, but blue isn’t the kind of color that really needs one. I’ll try to fix it, though. The color also needs one or two cards in the latter part of the curve.
Otherwise, counters, card draw and maybe a trick or two.
About two thirds of the white cards thusfar are creatures, which is a tad more than in normal sets, and their curve is pretty good. Now reason to mess with that. Maybe around ten of these should be creatures and maybe with a somewhat higher curve than before. On the other hand, there isn’t much removal, so I should emphasize that.
At this point, I have 225 cards in the cube. All the Gods have been taken care of (for now), so its time to move on to other stuff.
