Haha, to be honest, I'd love to get that deck. xD
But I doubt you're looking to give it away. In which case, keep it as a regular use deck. Try out any new flourishes and sleights with the deck. It won't matter if it gets bent, or creased, or if you drop it in a puddle. It doesn't matter what happens to it, because it's just 48 cards that you got for free, missing the deck box.
