Instrument crafting is becoming more popular in the rising star game. big players are interested to mint some unique cards to sustain their position on the leaders board.
If you're seeking for some unique cards the custom shop missions are best to mint some unique cards. but if you're new player and don't earn much starbits, then crafting is not good idea for you.
why...
You were thinking to ask to why, right?
The answer is here,
First of all you should understand what is crafting (Read F.A.Q).
You need 4 components to mint 1 card, 1 mission will give you 1 random component and the cost of the mission is 1000 starbits, but the story didn't end yet. every mission will give 1 component this is 100% true, but 4 missions will give you all 4 different components to mint a card, it's not possible, you can't get all four components in a row.
here is an example
let's suppose you want to craft production instruments.
you need mixer, penal, monitor, and speaker to mint 1 card.
you start productions crafting mission and you will get some random components like, 2 speakers 1 mixer 1 penal or 3 speaker 1 penal, or 2 penal 1 monitor 1 speaker. no one can tell you how much missions you need to complete for all 4 components.
I completed 22 missions to get 3 drum instruments and I've 10 components left.
Here is my 3 drum instrument cards

If you earn more than 20k SB everyday then the crafting is better way to get instrument cards for increasing skill per mission from music lessons.
