Hello @merthin :)
Thank you for reading my tutorial
I'm glad you liked it
I wrote the tutorial months ago and there have been subsequent updates in the game but the basic information is still valid.
You could use these two posts I wrote more recently in which I explain how I choose the cards to buy:

• https://peakd.com/hive-146620/@libertycrypto27/dcity-how-to-choose-the-cards-to-buy-come-scegliere-le-carte-da-comprare-eng-ita

Thanks also for the tip :)
Have a nice day
