This Vanguard card came with a set up upgraded blasters for Classics Thundercracker. I regret not buying the other sets in this series now as they make the figure that much better and come with these awesome cards!
From the canceled Mach 5 release, Mech Ideas picked up both Gauntlet and Piston. Gauntlet here is heavily inspired by IDW's design of the Wrecker, Ironfist.
Keeping with the 3rd party theme, I finally found the other two "Insecticon" cards from FansProject.
