I didn't know you can't play two of the same command card at the same time until a week or two ago as well, which also means those trooper lists can only reinforce ONCE in a round regardless of having the two cards or recycling with Leia.
Huh. I'm not really sure about that interpretation. The rules specify you cannot play multiple copies of the same command card at the same time, then goes on to give an example of stacking Accuracy. But what about sequentially? Sure, you can't use Explosive Weaponry to go to Blast 2, but Reinforcements played twice, particularly on two different groups, doesn't have the same stacking effect. That should be clarified.
