Other similar games like Hearthstone have a statistics of how many cards you have of different cost in your deck. This is useful information as you’re building your deck.
It would also be nice to be able to see how much cinder cost of the abilities of your currently selected roster is. So it is easier to know if you picked more units than you’re likely going to be able to use abilities with.
It is a bit annoying to have to scroll up and down the list to double check.
