Brawl deck building bug, singleton caveat ignored. Deck is not playable
There is some issues with Persistent Petitioners. It is one of the cards that allows you to have "any number of this card on your deck"
But brawl is saying that my deck has an error of "too many copies of the same card"
Obviously, ignoring the card's caveat to the rule.
It's one of my best decks, I'd like to be able to play it.14 votes -
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
I tried going to settings and using Repair game files on the Report a bug settings page. The problem persists. It appears my ownership of one…

FDN Collection Count Incorrect
the Foundation count is completely crap. I had 23 commons that I was missing (i.e. that I didn't have any single copy of), even though my collection count told me that I had collected at least 1 of every common in the set. Crafting 1x of those missing commons didn't change my count at all, so obviously those commons that I crafted didn't exist in the set.....
So - my request is that you get the count correct for the FOUNDATION set collection. Given that that set seems to be much bigger than the other sets I guess that the…14 votes -
Wrong pet showing
If I choose the Peaceful Pup pet for a deck (using the deck editing tool, since Pup is not my Default Pet) the game will actually show Hunter's Hound instead of what I chose.

Side board issues
For some reason I can’t have more than 7 cards in my side board, and every time I try to put in any number between 8 and 15 cards in the side board, it says “decks cannot have more than 15 cards in the side deck.” It says this both for new decks and existing ones

Deck builder Sideboard cant count.
In deckbuilder, if sideboard has 8 or more cards the client will not save the deck and reports that “a deck can not gave more than 15 cards in the sideboard”. There were 8.
I tried with other cards and other sideboard sizes. 7 or less is fine. 8-15 is bugged to automatically think its more than 15.
I saved the deck with a small sideboard then reopened the deck and still encountered the bug.13 votes -

Unable to add cards to draft deck due to alternate art
I am unable to add triomes to my draft deck in chromatic cube draft. The triomes have alternate art and when I try to add them I get the following message: This cannot be played in the current alchemy format. The only alternative is buying the alternative card style, which Ido not wish to do. I drafted the card, so I would like to add it to my deck.

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
