You only have 5 offensive cards in a deck. And it's not even a stall deck. Even if you manage to lock down your opponent completely, I find it hard to believe that you have much offensive power. If those pulvys get RT'd or killed off, you seem to be a sitting duck. Most upped decks also use SN, so quicksand isn't useful either. I suggest using BH, since you already have the mark of gravity, as that will help you to faster lock down opponents and defeat SNbows. I'd also take out 2 pulvies, and the animate weapons, and see if I can fit in some elite chargers (or steel golems) as well for damage.
