Hi, everyone. This came up in a game I played in yesterday. My opponent was running Darth Vader as his commander. At one point he used Vader multiple times during an attack, using more than one token to reroll some dice more than once.
My assumption is that Vader can only be used once per attack. His was that he could be used multiple times, as the trigger is simply "while attacking", which would continue occurring until it was resolved. Now, Vader explicitly states "1 defense token". Admonition, on the other hand, has a similar wording but says "a defense token". I'm thinking that would be interpreted in the same way. If either of those can be used more than once during the same attack/defense, then what is to stop you from re-rolling over and over with Ordnance Experts, as it contains the same trigger of "while attacking" as does Vader.
To me all of this points to a single use per attack. Is this correct? I could not find any strong guidelines on triggers and card use in the rulebooks or FAQ. Thanks for any help!
