i would agree, should an aggro shaman come into the meta, this card will gain value, as it will allow to draw into the cards you need, this is of course past turn 5 or 6, where you should be either winning or losing the game at that point.  much like other class cards,  if you are winning it will most likely push you that much closer, if you are losing this card really does almost nothing, as it does not conserve mana,  any card you draw would have been playable on the turn you used far sight, in a losing situation, this card simply limits the options your deck has to come back and win.  in a hyper aggro deck this would be a very powerful card, as you are looking to win early in the game, and having 30 cards is usually  not necessary, so far sight thins your deck, getting you better access to the cards you need and possibly gives a big creature to play early, though this is the lesser of two situations, more likely is it will let you play something like argent commander and reckless rocketeer ( leeroy) on the same turn.  in the case of leeroy you will have enough mana left to double rockbiter or windfury.

shadowmourne could be reworked to a more apt set of attributes
