Help with Card

Use a matrix visual. Put the Status column in the Rows, then put your measure in the Values. It should just show one row for "A" with the count value next to it, but if it shows the other statuses, you can use a visual level filter to remove them. If users click on that one row, it should act as a slicer for other visuals. You can use the formatting options to make the text larger, etc. to replace some of the general look of the card visual.
