So the latest preview article introduces a lovely little card called Minefield Mapper that lets you throw out your bombs before the game begins. Won't do much with bombs that detonate at the end of the Activation phase, because of the range limits, but Proximity Mines and Cluster Mines will love it. Especially if it happens to work with Extra Munitions. If it does, a TIE Punisher with two sets of Cluster Mines, Extra Munitions and a Minefield Mapper could blanket the midfield with a string of twelve mine tokens!
Question is, when you're discarding your bomb upgrade cards, must you only discard the ordnance tokens instead of the cards, or can you, by discarding "any number" of cards, discard the same card twice, once as an ordnance token and once as itself?
