But I'll ask anyway Where in the world is Subeta listed in the Ultimate Gaming Card Games? because I can't find it anywhere....Or do I just go to pay by cash and redeem the card there?

Theres a link in the cash shop for buy CSC where it says pay by cash/UGC. You click this and it has you put in your card number.

@ Mythology

You go to the Cash Shop and click credits. From there you find the amount your card is for and click Pay By Cash/UGC.

Edit: Whoops, too late.

Ah, Okay Thanks guys!

UGC = Ultimate Game Card :)
