5X is just another efficiency list. Limit the number of R1-2 shots an individual ship takes from them on the opening turn of engagement, which means using obstacles against them to split their forces and limit their movement.

Boba Fenn you try and zone Fenn out of the fight long enough to deal with Boba. If they decide to yolo with Fenn, punish that mistake.

In playing a friend's Boba/Fenn list, we talked a little about what to do to counter it afterwards - he was of the opinion that you need to commit to Boba, as I've seen elsewhere on the forums, with the swarm. The problem is that when you do that, you give Boba all the passive mods he wants, as well as some active ones. You need to be prepared to take some heavy losses to the swarm if your dice aren't behaving, so work around that. At the time, I was flying a six-ship swarm with DBS-32C and five tougher Vultures. I made some adjustments after that, with the knowledge that if I'm flying 32C, I'm going to want more ships. The revised version is a 7-Ship swarm (5 Vultures, 2 Hyenas) that bulks up the Hyenas a bit and plans for disposable Vultures. I think, though, that if I were to use a swarm against that list, I'd think more about an 0-66 + 5 Vultures model to give it some staying power to survive against Fenn creeping in from the back and blasting away.

I think Hyenas are better against Boba/Fenn because it is unlikely that a Hyena will be one shotted, meaning both ships will need to commit to taking one ship off the board.
If it was a Vulture, both ships would have no issue closing in and wiping out a little brother.
I never fly swarms, but I think I might try a Hyena list.
