> does it simply skew deckbuilding into a new "broken"

exactly, that's why it probably isn't feasible other than casual/social play: there's no change to the fundamental rules that doesn't end up warping the meta-game. (Particularly if the fix relates to mitigating mana flood/screw with consistency: I suspect it rewards combo lists, whose win-cons are indistinguishable from "find three specific cards".)
