Even though it's a Sorcery, Forked Bolt is probably enough better than Dual Shot to consider the latter unplayable. The difference between Instant and Sorcery is largely mitigated by only costing one mana.
As per the OP, the werewolf reminds me a lot of this card:
While there are a ton of obvious differences, I imagine the majority of decks that would want to play the werewolf would want the Storyteller even more, and the Storyteller is basically unplayable. It's not a perfect comparison by any means, but the Storyteller seeing virtually no play is a good indication that this won't either. And as other have said, if you want to punish your opponent for interacting, the cards that prevent it altogether likely accomplish your goal even better.
