The current list I'm looking at is pretty simple:
OGP with the title and Palpatine, designed to run around the edge and play bait, taking advantage of the board wide target locks and Palp's ability in the meantime.
Commander Alozen with VI, Tie/X1 title, and ATC. Can get easy target locks, flying around and providing supports while getting cheap crits.
Then there's Vessery, running VI and Cluster Missiles. He takes advantage of all the free target locks, and on bigger targets is able to get off Cluster Missile with an extra target lock for each attack.
I'm not convinced this is the best build, but it sounds insanely fun, and I'm curious what other people are planning on trying.
