Hey ekavieka,
yes it's always good to update your deck and see what works and what not. The cards in the star store are off-chain at the moment. The easiest thing to remember is that if a card has a lock on it, you cannot sell it. It needs to be forged first, which will require a certain combination of FLUX + $GODS = NFT. I hope this clears the air a bit for you. The welcome cards.. the purple ones are to be minted on the network and later traded. If it doesn't have a lock you will be able to trade it soon. I don't think any of the Welcome cards from the star store are minted as NFT's, but you can always ask someone from the team in Discord group and they will be happy to help you. I don't have all the answers I just play the game like you. Not related to the official GU team. Good luck with the weekend airdrops !!! I will be posting some more F2P decks in the future, so drop a follow if you want some helpful hints on how to build a competitive deck. Also, if you want to learn even faster, I would suggest to go on Twitch.tv and search for GodsUnchained related content. There are a lot of really good players from which you can learn a ton!
Thanks man, your explanation is already such a great help for me. it is a good game, but I always need to learn a lot from the other player.
I will sign up for twitch after I get a better internet connection so that I can learn better with good connection, also as I hardly go to twitch lol.
I am still stuck at purified iron, it is the lowest rank to be eligible for the weekend airdrops. let's see If i could receive some token by the end of the week. because my shield for the purified iron is almost broken.
