The more I play with this deck, the less I like Interference. It's good in the right situation, namely when an opponent like Jerry has no use for their SE, but opponents like that are few and far between. Most of the time, however, even with Shadowvein, the opponent is doing as much with their energy boost as you are, albeit not for the same level of value. Against a Boris, for example, I'd rather play my allies (as long as it's at least two at a time) for him to deal with rather than make 12 cards in my deck dead draws in exchange for a big Interference late in the game. I'm going to try a 3-1 split, which is probably more acceptable.
