You call them and request a replacement, and typically give them a team or a few players that you would like. For example you could request other St. Louis Blues, and then they would just randomly pick something of "equal" value from what they have in stock. Sometimes you get what you ask for, sometimes you don't.

Got it. Thanks a lot for the info. I'll probably just stick to my guns and wait on the Tarasenko since it would be such a sweet card and hope I get it sometime in the next year or two.
