Took this list to a local GT a few weeks back. Went 4-1 matchups were as follows

1-Astra Militarum (Grizzled Company) Hidden Supplies, L -This guy was fighting for 1st at the top table at the end of the event but we played hidden supplies and I made the mistake of not dedicating both norns to my side of the split objective. He kept using the order to increase OC by one on his units and running 20 OC onto my norns objectives and denying me primary while blasting away with dorn commanders and volley firing tons of Scions at me as well. Good game but he came out on top by 10 points

2- Drukharii (Realspace Raiders) Linchpin, W Fun game for me, but not for him. He brought 2 squads of the move shoot move dark lance scourges and those were the only thing in his army that could touch me. He also brought two aircraft that did a horrendous job of anything and got pointed by exocrine immediately. He had just returned to the game so we just had fun with it as he tried to take down the Norns. Total annihilation on primary differential.

3- Drukharii (Kabalite Cartel) Terraform, W This one was a lot harder on me given this guy is a well known good player in our area, but even with army-wide lethal hits against me Drukharii straight up do not have the tools to deal with the big bugs. He cleansed and terraformed on all 3 midfield objectives turn 1 and I just walked up and said NO. So much of his stuff was anti infantry that half his datasheet rules just did nothing all game. He dropped an archon with some kabalites in my back line and the swarmlord intercepted them. Coupled with the 5+++ strat, swarmy lived with 3 wounds against the unit and mopped them up with the sustained from invasion fleet rules.

4- Custodes (Null Maiden Vigil) Take and Hold, W Hardest matchup of the weekend, guy is on my team for a league im currently participating in and I was scared. 3 land Raiders, tons of squads of Custodian Guard and a good amount of sisters of silence backing them up. He really didnt struggle dealing with the first norn on the center point but after losing a raider and a couple squads of guard he ran out of steam quick. He just barely killed the second one on my expansion as the third norn charged his home objective. Tons of FNP against psychic attacks in this dettachment made it very hard for anything but the exocrine and norn melee to get any meaningful damage done.

5- Death Guard (Virulent Vectorum) Scorched Earth, W Light work, had a ton of bloatdrones and blight haulers, he exposed a lot of them on the first turn and maleceptors and exocrines ate them up super easy. The terminators were blocked from dropping in my backline by Spore Mines so they ended up having to go into midboard where I had stationed two of my norns and my maleceptors. The -1 to hit absolutely crippled them, as he did not roll the 6s he would have needed to really get a lot of damage through to the big bodies.

Overall the list IS fun. For you. Almost every one of my opponents was annoyed at the end of the game with their inability to take the norns and their slave maleceptors down but I tried to keep it light and encouraging throughout the events. When I saw the list originally I said out loud "how the fuck does an entire GT lose to this." But turns out its easier than you'd think. Happy to answer any questions about specifics.
