It's a good start, but IMO he doesn't work with the Vipers well.
Once you put OMs on Venoc Vipers, you have to keep them on them or else they die. With this guy you are hoping your opponent is close enough to use the Venoc Hunter, and where you have Vipers that can strike and won't die on you later on. Very hard to pull off.
