New Game: Magnet Chess Solitaire

Similar to Neighbour Chess Solitaire, but pieces can pull an opposing piece towards them or swap places with an opposing piece.
Deal out 8 cards, and place the pieces as in Chess Golf. Then spend the other 8 cards, either face up to add the piece to the board, or face down to make a swap or pull move. If you run out of cards, turn them all face down, then spend them as negative points to make swap or pull moves.
Goal: get all the pieces in a connected group, diagonal connections count.
Score: If you reach the goal before running out of cards, 1 point for every card you have left. If you run out of cards, -1 point for every card you spent after that.
