Decks Invalid
All my decks are invalid for the format Im trying to play (For example, Pioneer). When I try to check why this is happening, is because there is an error with the Sideboard.
It keeps telling me that I have more than 15 cards on my sideboard, even with 0 cards on it.4 votes -

Duplication of legally duplicate cards in braw, incorrect rules interactions
After the update yesterday a brawl deck is no longer considered legal. I have multiple copies of [[Shadowborn Apostle]] which states that “a deck can have any number of cards named Shadowborn Apostle” yet I am getting the error message saying that I have too many copies of a card. Other than that, the deck is singleton…

Sideboard is incorrectly counting cards
When the last patch 2025.49.50 was installed some decks became unusable, because the game says they have the incorrect number of sideboard cards, despite them having the correct number (15 cards). Also I cannot save decks for the same reason. If I put more than seven cards, if says it cannot have more than 15 cards and I cannot save the deck.

Cards in deck are different than they were a few days ago
- No idea how to reproduce this, it's just something that now exists
- PC
- When I logged on today, my deck which was a Brawl deck with The First Sliver as my commander is full of different cards. I've never seen this combination of cards before, it's definitely not what my deck was previously
- nil
- I could show you the new deck, but without the old deck I'm not sure it's relevant
- None, other than rebuilding my old deck. But I don't recall all the cards

Cant add cards to deck or sideboard
When creating a deck, it often won't let me add more of the same card by hitting the + sign. Also, as of this most recent update, it almost never let's me add cards to my sideboard during deck construction.

Draft deck wont submit
I drafted using my android phone of the new set. When I went to submit my deck it said it was invalid. I've tried the fix a bug reload option a dozen times, between my phone and my apple tablet and nothing has fixed it. The system seems to be hung up on the lightening strikes I drafted. I would love to be drafting this new set as it looks like I'd spend money on it and did for the initial draft. But at this point I'm about over playing this game.

Banishing Light requires common wildcard for same visualization I already have 4 of
On Windows 10. Specific card affected is the Jumpstart Banishing Light. Obviously I have a common wildcard to spare but this bug could be serious if it repeats on a card at rare or mythic.

set completionist II achievement not working
- Steps to reproduce the bug - acquire 4 copies of each card in an alchemy set
- Platform I am using - PC
- Result I was experiencing - achievement did not unlock
- Expected results - Set completionist II achievement unlocked
- Screenshots - see below
- Workaround - Fix notes on the achievement to reflect restrictions/conditions that alchemy sets don't count or fix the achievement to unlock when an alchemy set is completed
As a side note I spent between 50,000 to 60,000 in coins as well as several mythic and rare wildcards to complete this set to not have the achievement unlock…
