All the comments are valid and quite interesting. With the Advent of Wave two bringing us engine upgrades and shield upgrades. Consider System upgrades such as harking the days of good old X-Wing flight simulator.
I feel as though it would bring a different element into the game. In X-Wing and Tie Fighter flight simulators, even X-Wing vs. Tie Fighter, you can divert power from your weapons, shields, and engines respectively. Here are my two cents:
Switch Deflectors- cost 4
Action: Reduce your Agility or Firepower by 1 to gain 1 Shield token until end of turn.
Primary Overcharge- cost 4
Action: Reduce your Agility or shields by 1 to gain 1 to your Firepower until end of turn. You regain your loss shield token during the end phase.
Speed Freak - cost 4
Action Reduce your Firepower or shields by 1 to gain 1 Agility until endo of turn. You regain your loss shield token during the end phase.
Damage Control - cost 4
Action: Reduce your firepower, shields, or agility by 1 until endo of turn to flip a Crital Effect or discard a Damage Card. Discard this card after use.
Opinions??
