GW Enchantments is too narrow and has no archetype overlap with other colors.
GW now cares about +1/+1 counters and synergizes well with GR 4 power matters.
UB was general "control" which is fine but m21 had reanimator as an archetype for UB and I decided to adapt it for this cube. With 6 reanimation spells in the cube you'll still be playing control, too.
