I'm not using your exact deck, but I've been using a similar deck and gotten to legend this month and last with it. But I do know how uninteractive it is; it's just slow and does nothing until suddenly a couple of From De Other Sides come out of nowhere and destroys them.
Gotta say though, Glugg the Gulper has won me many games. I think it's because I play slowly and they think I'm just playing a generic control shaman with no game plan. Play it on turn 9, they don't remove it because they don't see me as a proactive threat and let their guard down and then From De Other Side can buff it by 20-25 Attack very easily while removing any taunt they could have.
All in all, yeah, I'm definitely a fan of the card
