Some of you have already touched on this new type of card, but the discussion on Tomax got me to thinking. When you are instructed to discard a card, you flip it face down. With that in mind, I think this type of card could have very interesting applications with ordnance cards.
They all have instructions to discard the card to preform the attack, and with a different weapon printed on the back it would reason that you could use it again. Something like:
Swarm Missiles
Attack (Target Lock)
Discard this card and spend your target lock to preform this attack.
Insert what ever these missiles do here.
Then on the other side....
Hyper-spatial Torpedoes
Attack (Focus)
Discard this card to preform this attack.
Again, further effects here.
Obviously, this could mean a high cost card, or keep the power mild and the price to match. Could be cool.
