If an upgrade card does not specifically say to Exhaust the card on use, can it be assumed that it's effect may be triggered multiple times in a turn (assuming it is obeying all normal game rules)?
For example:
Is Dominator allowed to drain it's hull zones more than once per turn to enhance it's attacks?
Does Gallant Haven reduce damage dealt to as many squadrons within Distance 1 that are dealt damage?
Likewise for weapon cards and crew cards, etc. etc.
