will core cards be tradeable after fusing them

From my understanding that is how its suppose to work. We will have to wait and see if that is what happens.

If you end up needing to pay gas and material to fuse those core cards and activate them to be on the blockchain it might not be worthwhile since the supply for most of those cards will be so high.

We can also expect a lot of alt accounts, people botting, and other stuff. Which will have a heavy impact on the core cards. It will be interesting to see how they choose to combat that type of behavior.
