Just pulled Ultron Chase!

I just pulled Ultron #55a (or maybe it was b), the 300 point Ultron chase from the Age of Ultron booster. I think it is the Age of Ultron movie version (the Phalanx is the one with 6 arms isnt it?) My question for all of you guys is should I keep it or put it up on ebay? I am mostly a casual player but I do love my tentpole figures. However, I dont play Ultrons very much so not really sure how much I would use it. Some of them seem to go for a decent price on ebay but if it could be better used to win a few games i might hang on to it. Any opinions?
