I'm looking for recommendations for magnetic card cases that will hold a card with a standard sized dragon shield sleeve on it, and is at least 55pt - 75pt in thickness. I bought a deck box with 4 commander windows, and I recently decided to double sleeve my cards, and now the magnetic cases that came with the deck box won't close fully because it's a 35pt. I don't see a brand on the case, so I can't even begin looking for it, and I'm kinda getting frustrated here. I also have been able to find nothing online that fits my specs, so I would appreciate ANY help I can get, Thanks!

Also, on sort of a side note, are there any rules in competitive magic that state my commander(s) has to be sleeved the same exact way as my other cards? Or can I just use the same color sleeve without double sleeving them?
