The combo and aggro versions really feel rough in the all the testing / leagues that I've tried to run so far. The control version (with Workshop) seem by far the best builds right now, but I think that may just be because its easier to build that variant (you can take so many things from Shops). I think in a similar fashion, the combo/aggro versions, probably need to borrow more powerful interactions from a decks like Survival, BUG, or Storm to give it some powerful things to do when it doesn't manage to resolve its multi-card combos.
This article seems more about net decking than any particular deck. To which there is a truly obscene amount of net decking on MODO. It’s not even just the good decks anymore. So the format then gets littered with these suboptimal trash deck builds that get played because someone recognized the name of the deck builder. There is such an incredible amount of variance and luck in Vintage matches that it doesn’t really matter though. Win a die roll and you are favored with pretty much any pile.
