What I did was I took the image of the mirror from the info screen in-game and just added it on top of an "Epic Card" purple border. I then took a screenshot of the Mirror + Epic Border while it was on a white background.

I don't have any advanced photoshop software – just Preview – so I don't think I'll be able to remove the white background without also completely removing the purple border. But based on your Doom Cannon image in the Boom Beach Wiki, where you kept the blue glow, you might be able to remove the background somehow.
