i like loose ends -- makes the reader think more. (i can self-justify the poor organization for days)
4c goodstuff fallacy: i can't find my earlier unpacking of the '4c good stuff fallacy,' but the gist is that too small a number of archetypes is also bad for a draft format, as are picks becoming too context-dependent -- like, what fun is it to get locked into one deck with your first several picks (especially if it may not even materialize), and to draft that deck over and over again in that single format? Gatecrash illustrates that danger. much richer to have dynamic tensions between fixing / spells, power / consistency, and so on -- one way of looking at the fallacy is that they're viewing a draft as if it were constructed, instead of something where you have a finite number of picks to cobble together a deck. decks that do a number of things are also more fun than decks with linear strategies, and the process of mixing and matching fixing, removal, a curve, etc. feels like the right amount of variables to achieve satisfying complexity. (also, it's good for replay value.)
beyond decks that are 'clique' and not 'goyf' there are any number of other parallels to be made with how i think about cube, viz. cards should fit in multiple archetypes, any deck should be possible, you cut fewer spells when you take more fixing ...
another point is that they shouldn't print so many damn multicolor cards (the density of mc in this block is higher than RGD -- 249/664 = .375, vs. 183/646 = .28) if they're not gonna let us cast 'em. "support the cards you have" is an important limited design principle. getting color-screwed a ton -- increasing variance -- seems like a poor way to make a format hard to 'solve'
my best guess is that RGD's particular magic is due to good color-balance, strong fixing, a million cards that say 'draw a card' (incl. common lands!), creatures with activated abilities, a flattish power curve, etc. which result in the complex, interactive, difficult board states that are a hallmark of that format. but i cannot hope to be descriptive enough.
the other day on facebook someone wrote that wizards is tryna kill cube, that would make the modo cube make a lot more sense. im gonna try to ply this person with booze
