User Reviews

Initially this seemed to work well, but I've noticed that the deck import from Moxfield doesn't actually work correctly. It iterated through all of my Commander decks, for instance, and all of them are missing 10-15 cards, sometimes more. I only realized it because it was telling me I had some specific cards available that I knew I didn't. If you manually add a deck it will have the right number of cards, but I'm not going to do that for 50 decks.

Is MTG Collection Lens Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

MTG Collection Lens requires a few sensitive permissions. Exercise caution before installing.
