I would say yes if you are building an deck with the goal of milling an opponent out. I have played against a deck where this saw use. It combos well with cards like Mirko Vosk, Mind Drinker.
I really enjoy Eight-and-a-Half-Tails You can do a lot of different things with this general. You can swap out 15 cards and make a completely different deck.
