I think some of us Entropy/Rainbow users have had those times when there are so many creatures on the field that you can't see the stats for your creatures in the top row, due to middle-row creature blockage. This is especially annoying when you've used mutation on said top-row creatures, but you can't see their newly mutated abilities/stats. The fact that the game does not update the hover-over/pop-up card details for mutated creatures does not help, either. Therefore, I propose a transparency-effect for creatures that are directly above the one that is hovered-over with the mouse.
