Does Static Discharge Vanes (SDV) see that much meta play and if so, what are those lists? I think that the card ability is neat but I am confused about the cost. I could be biased but I would like to know what you all have seen...

It doesn't see much if any meta play. It costs as much as it does because it is a way to ensure a target receives an Ion Token and most likely, definitely in the case of small ships, become Ionized rendering their next maneuvers and actions in the following round completely predictable. Paired with Feedback Array on Illicit capable ships it is powerful, especially in mass. Now it is priced out of wide usability so we're looking mostly at Black One titled T-70s occasionally taking it to ditch the Ion token they can accrue in place of the disarm token from using the title. FFG did allot to nerf Ion weapons and the ability to apply Ion token in general as part of the reboot into 2.0.
