I thought the other day that a great 'crew card' would be a 'strategist' card.
It would allow you to , after normal deployment, move one or a number of ships to new locations.
Representing the fact that you had tricked the opponend to expect you to fight on the right side of the board but it was a feignt and you were really engaging from the left.
it could be a modification like 'decoy scanner drogues'
For eample, its 5pts and you roll 3 green dice, for each 'evade' you get you can reposition one of your ships.
I also thought another cool card could be 'stay in attack formation' its a 2pt EPT that allows you to *move* at the same time as the ship before you. Sort of a reverse 'swarm tactics' to allow you to move earlier than you normally would allowing a 'first firer' high PS ship to also make a blocking action
