Using Image Masking To Show Unmatched Content

I have a piece of video content that will change from one state to another (a poker card in a video. Changes from the back of the card, which is always the same, to the front, which is always different).

Using image masking (alpha-color) is exactly what I "want" to happen. I've made an image of the back of the card. When the video shows the back of the card (matching the image)... the mask hides it. When the video shows something else, the mask is dis-engaged and the video part shows.

The problem is that, with the alpha-color mask, it only shows the unmatched video very faintly.

Is there another way to go about doing this, or another filter I should add in somehow to make the unmatched content show as normal?

Truly appreciate the help!
