Cards reshuffling

Hi All,
I’m working on an interface, in which I want to create a grid of content cards that automatically animates a reshuffle when user grab one or several cards.
I have been trying various strategies to get it to work. Has anyone got any ideas for how to make this work?

I would be most grateful if there’s anyone who could help me out here and take a look at my file!

Thank you in advance,
