One side has guns that denies armor saves for Genestealers and Lictors so they'll be taking break tests by Turn 2 as 5 base Genestealers is over a third of your 200 points. And due to KT force org you could take a single Lictor. So if you can fit it you'd have 11 models that can't return fire and will likely be dead before they get the chance to engage. Better hope the terrain is set up like Space Hulk with plenty of corners and LoS blocking terrain. Cause that's the only chance the Nids player would have and the Lictor will be taking Synapse checks at the start of every Nids turn. Due to KT rules he would just have to fail once and if he's falling back he's removed.
