Thank you for clearing that up. One other thing, can cards without any abilities eventually get an ability upon upgrading them?
Also you say only rare cards will be blockchainixeable, but if I understand correctly, you can just upgrade basic cards to rare cards? So all cards can be blockchainizeable, only at their final form?
If you ask me upgrading cards that are not Legendary or Epic will be waste of founds.
as Shaban said maybe a week ago, there is not clear yet how blockanizatio will work, but that there will be limited number of cards you will be able to blockanitze. So some might blockanize 3 Common cards and some will wait and save their blockanization slots for Legendary ones. Things like this is best to just wait and see.
https://sogassets.com/here you have all cards and how they evolve. blockchain and ingame. and when you will think you know all of that website, take a nap and return and you will find soemthing new and then just repeat it again. it is really good website.
