The sideboard bug in MTG Arena Best-of-3 is incredibly frustrating — being unable to remove cards during sideboarding breaks competitive play. For more gaming and tech discussions, check out https://betifys.org/ . Have you encountered this issue on mobile or PC?

The game is rigged, don't give these people your money :) Don't say I didn't warn you

Maintenance just finished and this bug STILL has not been fixed. I abandoned MtG for 8 months partially because of how buggy Arena is and it's absurd that it's even WORSE than it was last year.

To be honest, I never expected it to work. After getting scammed of $88,540, I'd already kissed that money goodbye. Then I came across Resqprofirm via WhatsApp at +1 (985) 296-9146, and by email at Resqprofirm@gmail.com or Resqprofirm@aol.com. Like most people in my situation, I was doubtful. I didn't want to raise my hopes just to be let down again.

But something about the way they communicated made me take a chance. They were professional, never pushy, and didn't make over-the-top promises. They guided me step-by-step and kept me updated throughout. A few weeks later, I actually got my funds back something I genuinely thought was impossible.

It wasn't just about the money, though. It was about finally feeling like someone had my back. I'm truly grateful for what they did.

This issue isn’t resolved But their IT department just keeps marking requests to fix it as resolved.

Keep reopening your requests.
Eventually they’ll figure out how to fix it.

Happens on PC as well. Cards can't be moved from sideboard to maindeck during bo3 sideboarding. Still happens even after Marvel set updates.

Przypomina mi to sytuację z zeszłego roku, tuż po premierze dodatku Bloomburrow, kiedy to bug ze sideboardem był tak poważny, że Wizards musiał całkowicie wyłączyć kolejki BO3 w trybach Draft i Sealed . Wtedy również problem dotyczył niemożności dokonania zmian pomiędzy meczami. Miejmy nadzieję, że tym razem nie będzie aż tak drastycznie, ale biorąc pod uwagę skalę zgłoszeń i fakt, że problem pojawił się po aktualizacji, liczę na szybką reakcję ze strony deweloperów. W międzyczasie, jeśli szukacie chwili wytchnienia od tej frustracji, polecam sprawdzić ofertę na https://spinmama.pl Niezależnie od tego, czy problem zostanie szybko rozwiązany, czy też będziemy musieli uzbroić się w cierpliwość, miło jest mieć alternatywę na oderwanie myśli. Sam czasem tam zaglądam, żeby zresetować głowę po takich bugach.

Similar issue, but on PC. Could only remove cards, and not add them. I tried closing the game and steam was stuck on the gray "Stopping" button. Happened in a ranked game and caused rank loss even though I was unable to sideboard and was then unable to reopen game. Hope there's some compensation at the end of this, Hasbro is straight up squeezing money from people with the rate they release these sets and yet they can't prevent such a gamebreaking bug? Sad.

Change your deck view

The same, windows pc

Came back from a break during turtles. Android same issue. Thinking about leaving again.

I also cant add or remove cards on Android sideboarding in bo3. I am so sick of this game just not working

I’m using an IPad. Haven’t been able to remove cards in best of 3 Standard matches for weeks now, whilst sideboarding.

I’ve also just experienced this bug. Would love to play Bo3 on my phone but this is unacceptable if this big har been around for so long

How long will you allow this bug to continue? This is ridiculous.

Same on iOS.

Still an issue after the latest update:
2026.59.30.4645.1279316

Not resolved by repairing game files.

Breaks bo3.

I think these are all reports of the same issue:

In addition the "Capture Log" button doesn't seem to do anything, in case you're seeing nobody on iOS submitting a log to help with troubleshooting.

Cannot side board in best of 3 games.
