Flying for fun, I saved a set of star cards ~ is it better to change the black 54 or the drawings? Legend has it that how much is the equipment cost?

Have money to buy paintings, but have no money to buy Darth Vader. It is generally recommended to replace Darth Vader and build the most expensive sky stone, 120 yuan, with 40 such stones. You may not be able to create a legend for 3000 RMB. And when you build it, you have to charge a manufacturing fee, at least a few hundred yuan, and a lot of various materials. If you prepare enough RMB, you can create a legend. But from what you said, a set of star cards will be kept for a long time, so there is definitely not much RMB, so I don't want drawings. I recommend you to praise two more agents, which are much better than Darth Vader.
