When a card instructs you to spend a target lock or a token, I understand that the target lock or token is removed from the play area, and no longer effects gameplay.
However, when you spend a target lock or token, are you not allowed to use that specific target lock/token in the game again? In other words, are both players given an equal amount of focus and evade tokens that they will eventually run out of? And can one spacecraft acquire a target lock multiple times, or only once?
