The deck is a straight control deck, in a format where those decks almost always fail. They are just too slow.
With Smmenen's one-off mono-blue deck as an exception, every recent Control deck has a combo win, for example Tog, Control Slaver and Oath. 4CC doesn't win for the same reason.
I think "combo" is not the right word here. Playing Berserk or Oath of Druids is not a combo like active Welder+Mindslaver with Pentavus on table. "A BOMB" is a better world here and Tog or 4CC has BOMB like Yawgmoth's Will at least and what Landstill has? But You are right they are too slow (Landstill and 4CC)
I remeber UGR Landstill builds with Oaths and Darksteel Colossus in Sideboard now You may say "MeandeckOath is just like UGRLandstill after sideboarding+Orchards etc". Otherwords: meta has changed so Landstill has changed too etc.
