You end up hurting the midrange plan while simultaneously not specializing enough to help your combo (regardless of what the random combo being put into midrange soup is called). You end up with a worse deck than either pure fair or pure combo, as these pieces just trip over themselves.

Take Hierarch for instance, you're dumping your hand by playing it...in a deck that needs to dump its hand to make Noughts...that has to dump its hand to protect all this with FoW. Once this doesn't work you're a mana dork deck trying to draw through more dead topdecks (other Hierarchs and half of the A + B combo). You need the mana dork to be a credible threat by itself (i.e. DRS or Deathrite Monkey) to get away with this; otherwise your deck construction is losing to itself.
