Well the list is brutally simple as you can see Devastator Shoots first then Avenger blasts stuff with their Defense Tokens exhausted Also i added some counter against squadrons Also a nice bid to be the second player What do do you guys think will it work?

I don't think you need much of a bid. It will do fine as first player. Add Kallus to Vader's ship to make the counter (1) more dangerous. Then look at suppressor (always good with Avernger around) and maybe a slicer tool on one flotilla to turn off big carriers squad commands.

alternatively Wulff/vet captain and Shields to maximum.

Counter wont discourage most heavy bombers (5+ hit points) sadly. I'd be tempted to at least squeeze in a squadron speedbump, possibly dropping a Gozanti to free up points.

@Green Squadron 3 have a read of this https://community.fantasyflightgames.com/topic/270023-cardiff-regionals-2018-vaders-story-or-how-i-won-with-double-isds/ for my thoughts

I'm thinking xx9 turbolasers might do better than spinal on avenger:

This does come from the slightly skewed perspective of someone who most commonly plays imp vs rebel, but quite a few rebel ships are packing multiple braces, and in those cases avenger won't matter so much unless you can guarantee the accuracy to lock down the unspent one. (Also works well vs ships with multiple evades)

I'd also agree with the assessment that a small fighter screen is probably more effective than the laser turrets,

I personally would drop the turrets, cut a gozanti, and eat a little way into the bid to get a couple of named squadrons for a fighter screen.
