Did a couple test runs with this combo last night in this list:
Darth Vader
x1 title
Juke
Sensor Jammer
Echo
Juke
Sensor Jammer
Stygium Particle Accelerator
Carnor Jax
PTL
Autothrusters
100
The gist is obvious. Force them to have to use Focus on Defense with Juke, setting up Sensor Jammer to enhance your defense, or get them to take the damage to try to mitigate Sensor Jammer when they shoot back. If Carnor is in range, enemies get neither, so they get hit harder and punch back weaker (nice for a frail list). Echo with decloak can be very obnoxious as a blocker, denying actions altogether, and getting the free Evade to trigger Juke. Carnor is the "obvious" target, but you plan on turtling with him and Vader/Echo pound the opposition.
Is this a great list? No. But when you get it dug in at range 1, it is extremely satisfying. I took it against a TLT list and it did OK between the Autothrusters and Sensor Jammers, and with Juke pretty much got to pound Y-Wings as though they were Agility 0.
Just thought I'd share and see if anyone else has been having some fun with either of these cards lately.
