This is the sort of list that will have a lot of success against low agility ships that are easy to hit but will more likely fall flat against high agility ships. Autothrusters will also be your bane.

That said, I think it can do just fine at a low level tournament.

However, I think the list could be much improved. I don't think the Scyk is doing a whole lot for you, but if you want to keep it, at least drop the somewhat useless Stealth Device. Those 3 points can be used to improve the list quite a bit, imho:

a) get operations specialist on Dace (or even K4 droid). Ops Spec would be hugely useful and take advantage of Dace's High PS.

b) drop those unhinged mechs for much better R4 agromechs on the y-wings.

Ya dont see many 4 ship lists anymore. It is cool to see this, and I would like to see it in play, especially with said modifications.

I'm in agreement with blade_mercurial. I have a similar list, but for yours in particular, I would put K4 on Dace, replace one of the Y's with Kavil (likely adding R4 to him as well), and then fill out as needed.

Probably something like this:

HWK-290: · Dace Bonearm (23)
Veteran Instincts (1)
Twin Laser Turret (6)
K4 Security Droid (3)
Y-Wing: · Kavil (24)
Veteran Instincts (1)
Ion Cannon Turret (5)
R4 Agromech (2)
G-1A Starfighter: · Zuckuss (28)
Veteran Instincts (1)
Fire Control System (2)
Operations Specialist (3)
-- TOTAL ------- 99p. --

This gives you quite a bit of punching power, betters odds of sticking Ion, and at least simultaneous fire against PS9.
