Gameplay is fun! I like that you used this system to make like a puzzle card game. You should definitely make an endless mode with the system. It works with the puzzle system, but broken frog seems too OP without any action cost. With some polish and effects I can imagine this being a game I sit down and play for a while. Some suggestions for the game would be to add more placement based effects and give the option to skip placing a card to use the action later.
