How do you unlock Shadow Jago?

Been replaying Killer Instinct and I have no idea how to get him, some sites say you need to do certain requirements, others say he's download only.

Shadow Jago was an exclusive for that day one gold card. (Which I also miss) As far as I know, he was only available with day one gold, you can't purchase him through the game or unlock him. Your best would be to look for day one xbox live cards on ebay or amazon or you could just wait till iron galaxy releases him individually, which might not even happen but who knows it might. He plays exactly like regular Jago, only difference is his looks.

There are actually a few places by me that still have the Day One XBL Gold Cards. Mainly Toys R Us. Any chance the codes would be active?

@nikkycat: To be honest, I never bother to look for them but only because I feel that shadow Jago isn't worth my time. I guess Dave could look for them at Toys R Us depending were he lives of course.
