I like this card as a mid to late game answer to allies on the field. It clears the way for Fury to attack or it sweeps the field clean to remove threats to your hero. Either way the value of the card is difficult to overlook.
I can say without any fear of exaggeration that Multi-Shot won me a match at a regionals tournament. My opponent had brought out a Parvink from his graveyard and had the opportunity to recurse a second via a Medoc Spiritwarden (He chose to put some armor on the field instead). When my turn came I was able to remove his little gnome protector and deal an additional 2 damage to his hero. After that there was nothing he could do to stop me from using Fury or Sentry Gwynn from taking his hero out.
For a hunter deck, the value of Multi-Shot should not be overlooked.
