What's New in MTG Compendium

2.18.0

September 4, 2026

Precon Progress is live — a new leaderboard shows how close your collection gets to completing any preconstructed deck. Sign in with Apple now works properly on Android. Fixed a crash on launch when offline, plus navigation crashes. Squashed a bug that could downgrade paying Pro members. Fixed Mox chat action buttons (wishlist, library, deck, buy links, exports) that could silently fail. Mox can now act on several cards in one reply.

AI Assistant does not work

When trying to ask a question to Mox it never responds. My question disappears and the “Hi I’m Mox…” is all that is left

Sorry you encountered this - you're review helped up improve the experience. The issue you encountered should be fixed in your app version

Super Awesome Tool

I just found this and I am surprised at the features the app has. The bulk scan is nice to add all of your cards to your collection and it works really well. The idea of AI giving insights to your decks is smart.

Two things I wish was better, the card valuation tool gets a little messed up because it automatically assumes I have a rarer version of a card than I actually do and there is no way to select the card I do have. Not a big deal though.

The other, I would like there to be a way to export a list of the cards I have.

Thanks so much for this app!

Needs Improvement in Small Areas

Love the way it’s laid out and how you can choose deck style, get suggestions, build a deck, etc. This could be awesome. But there are small things that just become tedious and annoying.
1. I can’t bulk add cards. I have to go in to add a card, search it, scroll down to it, and then add it. Doing that process repeatedly sucks.
2. An extension of the previous point; I wish I could choose more than one type of card within one search. Having to reapply the same filters time and time again isn’t seamless.
3. Any time I minimize the app, it kicks me out of the search I was doing. I have to reapply filters and find the card I was looking for again.
