"Full Burst" will drop eventually. I've seen him at $6/ea.

Also, he's a participation prize in the free play so once BWC is over, the card should be a lot more common.

And, in Jack, Variable Cord will always be a dead draw cause you won't have the hand to fill his soul. And, if you do, you're likely giving up cards that could be used better... and then you'll draw Jack, lol. In the end, if it works for you, great. I avoid "backups" in my deck and just optimize it for my strategy. If the strategy doesn't come together, and I don't play intelligently, then I earned the loss.
