Excellent man 😀 When you already have a hive account you can simply log in with your current details using hivesigner and you're packs should be there. You will have to transfer them out onto hive-engine in order to sell them.

Go to the cards page and under 'inventory' you click the backpack icon to see ur other assets. From here you can get them out.

Yeah I am going to buy a few packs of the next new set and stick them away until the sell out.!!!
