Mobile drafting to sideboard not working correctly
The way mobile drafting worked for a long time was that when you had your sideboard open and drafted a card, it went to your sideboard. If you didn’t it went into your deck. This was great. For a while, the way it’s worked is that it instead depends on the state of whether your sideboard is open during the previous pick

Historic Metagame Event Bug - Sideboard issue
During the Historic Metagame Event, when going to sideboard, I was only able to access my Best on One sideboard cards, instead of the Best Of Three set. This caused me to be unable to sideboard my graveyard hate cards against reanimator decks, and I lost early on two seperate entries. I had tried a second time hoping it was just a one time glitch, but it continues to be consistent.

Sideboard Bug Bo3/ Problema con el sideboard Bo3
El sideboard jugando explorer bo3 da problemas, a veces haces click en las cartas y no te deja cambiarlas, si tienes por ejemplo kaheera y metes otra criatura que no es compatible se queda pillada la aplicación, incluso reseteando el cliente (en vez de quitar a kaheera automáticamente como sería lo lógico o preguntarte si la quieres quitar de compañero)
A veces salen imágenes blancas por el menú después de estos bugs.
Ojalá lo pudieran arreglar ya que el bo3 es un elemento clave del juego.The sideboard when playing explorer bo3 gives problems, sometimes you click on the cards…

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.

Can't Sideboard
Currently can't sideboard at all on BO3. Cards don't even show up - just the blank image attached below. The Done and Back buttons also do nothing, forcing me to restart the app and wait out the loading timer just to play the next game.

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.

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 the…6 votes -
Cant use full sideboard
During sideboarding, I can only see and use the first 7 cards in my sideboard despite having 15. The deck is saved as traditional timeless. Remaking the deck from scratch might fix the issue, but copying does not.

BO1 format decks with 15 sideboard cards treated as invalid decks.
- After the update on 7/9/2025, some BO1 format decks with 15 sideboard cards display the message "Invalid Cards: 0"
- These decks can no longer be selected as decks to use in BO1 format
- Before this update, BO3 decks could also be used in BO1.
- From now on, if you want to use the same deck in both BO3 and BO1, you will have to clone it and reduce sideboard cards in BO1 deck, which is a pain.
- Roll back this change immediately.
- If this is not okay, why does the sideboard display have a separator that says "Best of Three…

Deck construction only allowing 7 cards in sideboard
Issue seems to be related to the "Best of Three only" being used as a reference for a 15 card sideboard. Any card under this message turns the number of cards from white to red, so 7 cards are ok and 8 cards are not.

Swapping Between Deck and Sideboard while Deck Building
The version of the Arena app I am using (2024.44.0.2235.1106704) does not appear to support any swapping of cards between deck and sideboard while deck building. I have to remove a card from one, and then add it to the other after manually swapping between.
Either allow both Deck and Sideboard to be simultaneously visible, or provide some method for swapping cards between in a single step.
Thanks!4 votes -
The 15 card sideboard warning prevent editing or building sideboard. Great dissatisfier and devalues this product.
I suggest the sideboard problem be fixed. Screen says I have more than 15 cards. This is not true. It does not allow me to edit my sideboards. Already restarted my computer and repaired game files.

Sideboard not showing
I am playing Pioneer, and every time after a game is finished, I only get access to 7 of my 15 cards (Companion plus six cards) as if I'm playing Best of one instead of Best of three. I've tried duplicating the deck, reinstalling the game, and changing the deck from Traditional Pioneer to Pioneer and back, as well as attempting to see if I had the issue on Mobile, but I still did.
EDIT: The issue was the 16-card Sideboard. However, this is an issue that should still be addressed.

Playing Cards on Sideboard Issue
When I am playing with a deck that lets me bring things in from my sideboard, only a few of the cards are selectable to choose as the card I want to add to my hand from the side board.
I think i should be able to move any card from my sideboard to my hand but it only allows me certain ones.

Sideboard Erro during Metagame Challenge
Played a Historic Bo3 ranked match with a deck and had no problems. Entered the Historic Metagame Challenge with the same deck and, both after game 2 and after game 3, once I made my changes and hit Submit, the Sideboard disappeared and I couldn't do anything until the SB timer ran out, at which point the next game started WITHOUT the SB changes
