This list seems adequate against most armies, but I dont know if it has what it takes. this is composed mostly through careful study of the codex and other Hive articles and i havent bought the some of the models yet. Advice is most appreciated.

It's a good list, i'd maybe drop the hormagaunts for some hive guard. But nothing drastic.

Outflankin Tervigon, wave of Gargoyles and Trygon is a lot of target saturation to make sure your Devgaunts can go where they want, along with the Ymgarls and DoM coming in quicker to disrupt. HC would help your list a lot.
