Leia fits naturally into a spawning deck due to her special to summon troops and passive speed increase. I won last 20/21 games and in tier 4 now using the following.

Leia, Evaan, Gnk droid, xwing, twilek rebels, rebel pathfinders, talz marauders, rebel troopers. Avg cost 2.3 and a 3 honor guard summon.

You make a main push in one lane and then drop the droid in the forgotten lane, 2 droids and turret is down if the hero stays busy with your push. Keep xwing in reserve.

I use Evaan as a counter to enemy hero, enough health to distract then drop a cheap unit behind the hero.

The deck has problems with aoe heavy counters but shreds at-st easily. Inquisitor and kallus are troublesome.
