Playing Card animation Troubles

Hello, I am trying to make a playing card animation where the top of the cards are pulled back and then let go to go flipping off onto the table. Currently I have a single armature that can bend and move the cards but it is only one for all of the cards. I don’t know where I should go from here. Is there a modifier or a simulation I could do that would work well for this or will I have to just keyframe it manually?

Thanks for any help!
