It would be nice if some illicit cards were available to other factions more often. Like Rebel Renegades have them. So why not some Imperial Remnants that are risking some weird tactics to hold on to their reign? On a very limited basis, I think it would be kinda neat.
But full candor, I really don't like a lot of the illicit upgrades that are out as is. Too many of them just flip the game into NPE modes. The scum faction unfortunately excels at that in general actually. 😑
