After browsing through all the agenda cards, I find Lord Vader's command to be the most lacking :

2 cards are redundant(you can add Vader once for 1 influence on top of open group, or 1/mission if you manage to pass the relevant side mission).

The cards can still be used together, but the least I can say is that they don't synergize very well. Then the third card is a bit on the weak side (-5 deployment cost for 2 influence looks pretty costly to me, when high value target gives you + threat cost once per mission if you wound one hero for 2 influence, or + threat level for 1 influence for Imperial Informant).

Vader is pretty strong in skirmish, but there are many more things that could happen to him (he could be stunned a lot more for instance), and some key missions already feature Vader.

What are your thoughts about his agenda cards? Is it worth passing one of the other agenda sets to get him? If so, which one did you chose not to include?

I'll probably play it because Vader is fun and thematic.

I've got it in mine. Took out Retaliation. I want to play Vader.

Yeah, the Vader miniature, and ability to deploy him later in the campaign definately made it worthwhile.
