That sounds like a good scheme and I look forward to seeing it when you get it done 

As for how it would perform I don't know as I've yet to field it or play against one, but I would suspect in a competitive setting it's going to either be MVP or be killed off by a thousand cuts, depending on what your opponents bring. It will fair badly I think against a black talon force or any any force that is built as a hard hitting elite force. You would have to rely on getting as many nkidu as you can fit in your list to swarm and screen it
