I feel like this is a Doctor Who reference right?
Anyway, I only post this because it does something novel and new we have not seen yet, as it can disable a Walker at instant speed and can be played off shops. Not only does it tap it but it also turns off activated abilities for the turn. I am not sure if the energy cost and the CIPT makes it a non starter before we get going, at least until we see all the energy cards in the next set, but the effect is interesting enough in a deck that likely has enough on board power to attack the walker the next turn. It can tap a creature as well though so it plays nice with tangle wire when walkers are not around.
