Ah, adding on to my previous post, unless you're keeping cards so that you can evolve them in the future, only keep buffers, nullers, unleashers. The others have their seperate uses (like AOE or turn skip for AUB) but if your goal is only AWs then it's not really an issue. Meaning medal the rest.

For Medals, use them to buy ATK and DEF Arcanea and possible yellow Arcanea Succession. The others you should have enough of depending on how many aws you kill (I just keep getting all the other ones from killing aws and never had to buy any). Use the ATK and DEF ones to buff up GUR Huang Long since it will be useful unless you decide to spend money for cash cards; it's among the best that free cards have to offer.

Finally, if you use your FREE jewels in the correct manner, you can get all the inv, collection expansions, magic school lvl 10, 2x Yggasils (BP trees) within a year. I've played for a little over a year and I managed to get all these with only free jewels. (Some luck required in slots though).
