I think premium incubator should be like this
You can choose any 2 common,rare and epic unless it’s a touranament reward but you still get a random amount of DNA of it
Example:you open it and there’s a tab that says common.you click it and there’s a list of common you can only choose 2/3(i don’t remember) you chose Velo and DG2 You want half and half dna amount, but you get more Velo than DG2.
the same Goes to rare and epic
Legendary DNA is still random
