IN
—themeless themes: I've elaborated on this idea earlier but it's basically that I want "themes" without having to "support" them. e.g. incidental synergies like reckoner + blas act, morph, collected company
—one-card build-arounds: a similar idea. plus tutors to find them: demonic pact, evolutionary leap, living death, pyromancer's goggles, tezzeret agent of bolas
—some more artifacts / enchantments that more than one person wants but some people will pass on: eldrazi conscription, evolutionary leap
—fewer creatures (my cube was a little too combat-based, an overcorrection against conventional cubes)
—new cards ... i.e. 5 battle lands
OUT
—narrow cards (boros charm, cruel ultimatum—one-card build arounds that aren't built around enough, or narrow gold cards one could do without)
—cycling out old new cards: heir of the wilds, herald of torment, frontier siege;
—cycling out obsolescent cards: student of warfare
—cycling out cards i put in just so my curve looked low: sunlance
—cycling out unnecessary duplicates (so now only one hallowed fountain, but two godless shrines, due to battle lands)
