Very fun concept! I liked how much you had to consider friendly fire and positioning, and the sheer amount of different cards was impressive.
I think the way moving cards around could be slightly different though, it felt at the same time a bit too powerful being able to move a card anywhere, but also too weak only being able to move one every turn. Maybe something along the lines of allowing a total amount of spaces moved but being able to spread them out across multiple cards could work?
