Having just played a game to try out the starter deck, I don't think this is good for Peni. Discarding a tech is quite a cost, especially considering how most of them in your deck are your identity-specific ones which you need for your resources and abilities.
It's better if you have a deck where you don't mind throwing away cheap techs such as Energy Barrier which is fortunately in this deck. Building around it might not be too bad, but I can imagine other characters like Iron Man who have lots of tech out and can dig for them easily wouldn't mind playing this card. At the moment, I think it's very awkward and unless you build around it, won't find its way into many decks.
