Here is my attempt at a dual star destroyer fleet using Thrawn to keep the squadron pressure on the offensive.

I added the Gozanti and Strategic Advisor to get 4 activations.
The Gozanti / Comms Net will provide the token to activate the Intensify Firepower card.
I would set up Thrawn with at least two if not three Squadron Activation commands.
The Cymoons would primarily use Maneuver commands to keep on target and slow to 1 once red dice range is reached; then when fighters get close Thrawn would be used to activate the fighters to hopefully cripple any enemy squadrons to leave a ship to ship battle.
I was not sure if I would just accept 2nd player since I am mainly red dice or if I should bid for first player by dropping any upgrade cards.
