Cards not in my deck are in my deck when playing
I have a “dragon” deck with red/white/blue, no cards exist that can “create” cards into the deck during gameplay. I have had cards with the wrong colors (black/green) appearing in my deck during the game. Totallly bizarre and has cost me a couple of matches

Unable to use full sideboard when using companion
Started happening with release of Final Fantasy (I believe)
Notes:
Platform: PC
This bug only appears to be happening when creating new decks.
If I choose a deck with a companion that was already in "My Decks" before the update this bug does not happen.Steps:
1. Create a new traditional deck where companions are legal e.g. Timeless
2. Select a Companion (so far tested with both Lurrus and Yorion)
3. Create a full sideboard (full 15 cards)
4. When sideboarding:
Expected outcome: I see the full 15 cards and can use them
Outcome: I can only use…5 votes -
network error - unable to get collection
Can't get in to the main user interface. Can't attach a log when no access to the main menu.
Error displayed: Network error - unable to get collection.
The client asks either to reconnect, log off or check Arena status server (all operational).
Restarted my PC, restarted my internet modem+router. Still same error.
I logged in earlier 6 hours ago, no such problem.

Deck limit expansion system
With Multiple Set releases and frequency, 100 deck limits is not doing it anymore. Devs sent out new decks which count against limit sizes --even though they say it does not-- multiple posts have been about this, as a player of over 5 years, we should have a way to expand the Max number or the categories...or each category should each have their own limit#.... I have Decks for Historic from 2019...and to constantly have to delete or save text files in 2025 is not ideal, Please give us a larger limit given the amount of sets, and…

"A deck can contain anynumber of CARDNAME" cards are not working
Cards that are allowed more than 1 of in brawl (And I assume 4 of in other constructed sets, I have not explicitly tried) are registering as invalid. I have a Tempest Hawk deck and a Nazgul deck and both are now invalid this morning due to having too many of those cards in their respective decks.
To recreate, create a deck and add 5+ Nazgul or 5+ tempest hawk.
This is on the PC client.
The decks do not appear when you want to chose one to play, and appear as decks with errors when viewing…7 votes -
Repeated GREerror when playing old deck
I wanted to show my friend this old cheesy combo deck I used to play by pulling it into a bot game, but I got GRE error twice. Once when playing Mastermind's Acquisition, but then again in the next game after just playing guild summit. Seems replicable with this deck.

Shadowborne appostles deck not working in brawl. Error message read "Your deck contains too many copies of the same card"
After the newest patch, I tried to play brawl with my deck that contains 33 shadowborne aposttles. The deck appeared as invalid and when i checked the reason the deckbuilder said that the deck contained too many copies of the same card. no changes made to the deck before patch and suddenly it just didn't work. 2025.49.50.9127.1160287

Draft deck save corrupted, cannot edit deck or play in event
I entered the Avatar premier draft on Arena, drafted my deck, and edited it. My phone turned off while saving the edited deck. Now when i open it to attempt to edit it, or when I attempt to play in the event, i get a neverendinf “waiting for server” message. My other decks can be edited and i can play other events and formats without issue, but I can’t play this draft event at all.

draft deck order bug
I experienced a bug where the deck order was wrong. After one mulligan I put a card (a card which only one-of was in the deck) on the bottom of the library. No deck searching occurred in the match. However, I still drew that card after several turns. I check again after the match to confirm - and there was only one in the deck.
This appears to be an error in the deck ordering on the server side - I have attached the .log but this doesn't seem to be a client side issue.
I haven't been…1 vote -

Green Achievements in Starter Deck Duel
Hi! I've been using the UG deck in starter deck duel to get some of the achievements. I was able to make progress toward (and complete) "Fighting and Biting" just fine. However, in my most recent game, I was able to get a Deepfathom Echo up to 33 +1/+1 counters thanks to Bristly Bill and a patient opponent. I swung with the deepfathom echo, then conceded the game. To my surprise, I did not get the achievement for "Count the Counters" or "No, Bigger Than That" despite meeting both of those requirements. I am on a PC running Arena through…

Broken black deck.
Currently an endless loop broken deck build. If you have "Marauding Blight-Priest" and "Bloodthirsty Conqueror" in play, if either activate, they both keep activating until the opponent has lost the game. This needs fixing.

Opponent deck list after match
I think it would be nice if there was an option to see your opponent's deck list after a match. Sometimes I am playing against a bizarre deck, then I can only wonder what is in it because it doesn't happen to be a meta deck at the time.
