in battle, remove card after it is used (remaining cards would shift to the left)

[Necksahn]

I play with an iphone and i can't see all the cards unless I scroll to the right (which is where the war tactics cards tend to be). If used cards disappeared when used then all remaining cards would quickly all be available without needing to scroll to the right.

I can see why you're saying that, but remaining cards show your alive units each moment which is useful at times

How big is your screen and how long does it take to scroll back and forth?
Even without card icons the number of regular troop icons and tactic icons and generals would still require scrolling. Just have to live with it.

Or the fully deployed groups can be moved to the far right. This will help with faster deploying in general. Aside from Android lag, I often deploy my paratroopers too late simply because I am focusing on the right side of the bar. It's a matter of convenience if nothing else

Have iPhone X and Generals is another card that should be removed when used. Or maybe move used cards to the end so you can still get the active counts.

Having to scroll is annoying. More so when decoys tends to be the ones hidden on the far right.
