Proxied Doubt in an Imperial Unshakable list. Here's the vid:
Some thoughts:
Hard to really tell what the true value of doubt was in this game. It removed a very important focus token from a weequay at the end of round 1. It also gave Vader a lot of room to work without having to worry about getting splashed to16. People eventually are going to have to change their game plan for Vader in a doubt list, either by completely ignoring him or saving every last card they have just for him. I think the value of removing 1 focus early in the game is worth the point, everything else is gravy.
