Fleet Arena without Original Trilogy Falcon?

I was able to stay competitive (but not top 50 for crystals) with Thrawn-led Geonosians, Hound's Tooth, Cassian's U-Wing, and Poe. Spy, Soldier, and Tooth up front, use Thrawn's heal+Buffs first to give Spy and Soldier Offense Up, then use their specials to nuke the enemy Hound's Tooth. Bring Sun Fac as my first reinforcement. Second reinforcement was the U-Wing to take out their Falcon. Poe's there because people still try things occasionally where the best solution is a big giant shot.

I know I'm only listing three reinforcements. That's because I have completely forgotten who my fourth was. Normally the fight ended with Thrawn's ultimate after my second ship came in.
