Jump In cards not appearing in collection after use in matches
Cards that I played with in Jump In are not appearing in my collection, nor appearing when searched for crafting. Namely I picked several packs focusing on getting the master firebender Zuko twice, Airbender Aang (mythic white) and Katara (water ending 6 version} and don't have any of them. Nor Iroh Dragon of the West. There are also smaller cards missing despite having played with them in the jump in event.

Inconsistent ownership of cards between deck editor/library and Set Collection on Profile tab
I used wildcards to craft all the commons and uncommons from the new Magic: The Gathering━FINAL FANTASY set in a single transaction. There is a inconcistency between what is available in my library and what is recorded in the Set Collection data on my Profile tab. The Set Collection on the Profile tab shows 108/109 for uncommons tracking x1 ownership, and yet my library has all 109 uncommons available in the set with x4

Cannot change deck type Format and cannot change Companion in Deck Builder
With the latest updates for the PC version of the app/client from this week (Sunday Jan 5, 2026 - Saturday Jan 10, 2026), I cannot change the deck Format on any deck in the deck builder. The drop down menu is hiding behind the deck stats on the left side of the screen. Also, I cannot change the Companion in the deck builder. All of the non-default Companion options are gone from the left side of the screen.

Product suggestion
After the update. There is no longer an option to change the format of an existing deck.
Example, I want to change the existing deck from "Brawl" to "standard" and make some changes.
Last time, there is a drop down menu which will show all formats, now its blocked and unclickable.
Please check and debug. Thank you.

Duplicate cards
After the update that occurred yesterday (07/08/2025), the decks I was using with Persistent Petitioners, Relentless Rats, and Slimes are now not letting me use multiple copies of the same card in Brawl. It has deemed my deck invalid because I have duplicate cards however the card specifically allows for duplicates.
I'm on PC.
Thanks

Allow players to toggle off Alchemy cards
I would like to try out Brawl deck (Commander in paper) ideas for decks but I can't work out what it needs or what to change when I am playing people using Alchemy cards, why can't you let us turn the option off. Why do you have no interest in listening to players.....

Profile for Pioneer Masters Does Not Agree With the Deck Builder
My Profile says that I have not yet fully completed the Pioneer Masters set, but the deck builder does not show any more cards that I need to craft to fully complete the set. I have a four of everything according to the deck builder. The same thing can be said about the M19 core set as well.
