Went 3-1 at a 16 player tournament today and took 3rd. Lost in round 2 because I hadn't figured out how to optimally deploy them on round 0, but I figured it out in rounds 3 and 4. Importantly, rounds 3 and 4 were the first times I think I've ever killed 2 full health ships in 1 round of firing, certainly in 2.0. First I killed Jan and Blount in 1 round, even after he had managed to isolate and kill my Bandit at range 3 on the approach the previous turn. Next game I killed Redline and a TIE bomber on the first exchange and also exposed a Fuel Leak on their other TIE bomber with Concussion missiles, and only lost 1 Z that round (and only 2 total) even though 4 of them ate a trajectory'd proton bomb.
I think this list is way stronger than any 7-ship swarm I've seen or played so far. So the strategy is to use Swarm Tactics so all 6 ships are attacking at I5, which allows you to order your attacks in a way that maximizes the effects of your missiles and lock actions. You shoot with the Clusters and naked Zs first, doing some spread damage hopefully while still being able to concentrate fire. Then you attack with Airen Cracken's concussions, hopefully flipping up some damage cards. Then you use Cracken's ability to pass a lock action to the other Z with Concussions (who has focused) with perfect information of what ship should be attacked next in the case that you already managed to kill 1 ships (which is highly likely).
The barrel roll action on the Zs is a nice option to have now, there were several times during the tournament where a Barrel Roll off of Cracken's attack allowed one of my ships to attack that wouldn't have otherwise been able to, either because it had blocked their ship or been arc-dodged. He's also very unlikely to get attacked first I've noticed so long as you keep him in the back (but not too far back or he won't get to use his ability).
For my opening deployment, I've found that most players will counter deploy the Bandit by placing on the opposite corner and trying to force me to come across the rocks and turn into them, so a 4-ship staggered formation with the 2 concussion missile carriers deploying at a 45 degree angle next to the back 2 Talas and then doing a 3-straight the the 4 offset ships and and 1-bank in with the concussion carriers forms them into a vertical 2-wide column that can then turn in easily and become a 3-wide phalanx.
