Here's a squad list I tested out today which worked quite well for me. What do you think of it?

Whisper Phantom, Advanced Cloaking Device, Push The Limit, Fire Control Systems

Kagi Lambda, ST-321, shield upgrade

Academy Pilot

Academy Pilot

99

Basic idea was to go 99 to try and keep the initiative, have Kagi soak up firepower while the fighters move as a pair to keep the rebels busy as Whisper cloaks around getting in hits that will benefit the others. In my game tonight the rebel player struggled to target lock the TIEs and couldn't hit Whisper as, assuming I played it right, I'm able to focus + PTL and evade + stress or just evade twice and stress. Then get a hit in, auto Cloak and lock the enemy. Then decloak roll, green maneuver and do it all over again. Some turns I didn't have a good firing arc so instead of using PTL I just evaded and moved white/green so I could do green/white maneuvers and cloak the following turn.

My other consideration for the list was to drop the Lambda for more TIEs or another phantom, but having those extra 11 points of damage for the enemy to deal with (hull/shields) really helped. Even when my opponent tried to ignore the Lambda I can try using the other ships to draw them back into it's slowly moving arc of fire, and target lock whichever ship I think will get there first thanks to the upgrade. I'm quite new to x wing so I don't know how competitive it is, but I'm testing it out again tomorrow.

cant cloak with ADC while stressed PTL not good

I would swap shuttle for doom shuttle or

"Whisper" (32)
Veteran Instincts (1)
Fire-Control System (2)
Advanced Cloaking Device (4)

Bounty Hunter (33)
Recon Specialist (3)

Academy Pilot (12)

Academy Pilot (12)

This is what I came up with now. Could swap spells upgrade on the Lambda for gunner on the Phantom. I'm told this is quite a common type of build for using a phantom by a more experienced friend after showing him my list.

Although you could trigger PtL off of ACD. Maybe it will let you BR away or something similar.

With that said I'd say PtL isn't such a great idea on Whisper unless your metagame is all low PS ships and maybe even then. Stress is NOT a good thing for a Phantom. You may be able to decloak, perform a green maneuver, and then take an action but then you need to survive long enough to shoot again triggering ACD and you could then use that for PtL.

I'm really wondering what the deal with Kagi is. The enemy has to TL it so yay! If flown will Whisper shouldn't be getting shot at so the big fat cow is already a prime TL target compared to the cheap eyeballs. The unlimited range TL could be nice but it's not really getting used for anything special; a FCS would serve as well. Then you throw Vader on the shuttle to help ensure the death of a 37 point piece; when Vader is used it is ideally on a 24 suicide shuttle and that saves you 13 points which would buy you another TIE.

If you're looking for a scarier 37 point shuttle (although you could do it with less) you could try Jendon w/ FCS + Gunner + Engine Upgrade which is otherwise knows as a buzzsaw shuttle. With that setup you should be pickup up TLs with FCS and could use Jendon's ability to hand off the TL at the start of combat. With FCS+Gunner you can shoot, miss, pick up a TL, and then shoot again using Gunner and possibly spend the TL token you just gained.
