This is possibly Cable's greatest asset. A card that, once defeated, turns him into a 3-3-3 powerhouse for the rest of the game and lends both his forms the Psionic ability. Admittedly, cards that rely on Psionic are limited at the moment, but the +1 boost to all stats is more than worth the cost of entry.
Even better, Cable can pull this card during setup with his Alter-Ego ability, ensuring you get to take advantage of the victory condition as soon as possible. Even better than that, it costs nothing to put into play. This is literally as close as FFG has yet come to just giving us a boosted hero. I thoroughly enjoy the way they are dancing around their own power creep. It's fun to watch.
