Oops, I did it again... [ENDED]

So last time I made a topic about some stupid decisions I made...
and yep, you guessed it, well y0u didn't really because it's in the title, but nvm. I made another terrible choice yet again. ;A;

I was thinking of making a region-restricted GA (I didn't forget this time!) because I just sold a lot of cardz so I had money 2 spend.
And then I was looking at sales to determine what to give away... I saw Blockstorm and thought it looked good, so I BOUGHT A 4-PACK.
Turns out it was given away for free. Now there're three Blockstorms sitting in my inventory.

My fault for not looking at the list first. (ಥ⌣ಥ)

There might be a hidden GA train here somewhere... ;) [L1+, No region-restriction, Ends on the 10th]
Hint: Leads to jigidi puzzle (Format: http://www.jigidi.com/puzzle.php?id=XXXXXXXX)
(130 pieces, in honor one of the greatest TV shows -- Person of Interest), then to GA.
Note: Has sgtools verification. Nothing much, just basic stuff like no unactivated/multiple wins.
