Lothal Rebel/ FCS, Autoblaster turret, Rey, Hera

Dash/ PTL, Kanan, HLC, Title, Kanan, Engine upgrade

The Ghost goes down way too quickly and usually Dash has a hard time taking down Defenders by himself (that's probably your worst matchup, trip defenders).

Actually I don't think that list is too bad against Tri-Defenders. Yes the Ghost will probably not last long but that is the point of a cheap Lothal Rebel. It will take a minimum of 2 turns of dedicated firing to bring it down and that assumes your opponent rolls hot and the Lothal does not Evade or manage to get out of arc of some of the shots.

Dash with HLC stands a reasonable chance of burning through an /x7's token stack. Also the 2 most popular Defenders are the tag team of Vessery and Ryad which are PS6&5 respectively. This means that Dash at PS7 gets the full benefit of his Boost and BR to arc dodge the Defenders whilst still blazing away with his HLC. Defenders are tough but the lack of Autothrusters and the fact they rarely take SDs mean they do not reach Soontir levels of unkillability.
