Starter Deck Dual and Formats- Bug
I have completed all the deck challenges in the MTG ARENA Starter Deck Duel, but after the recent update this tutorial is stuck in the "resume" status on my home screen. There is nothing to resume, because the whole challenge is completed (already have all 10 decks), and therefore this flag will not clear.
In addition, I am not being able to access the others events and/or formats to play, like historic, draft, etc.

Invalid deck bug
After the update today a deck I have been using for months is being flagged as invalid. No cards in the deck appear as red/invalid and when I click save it says: “this deck contains too many copies of a card.” I have 9 nazgul in the deck as it states on the card you may have 9 copies in a deck, and Ive played hundreds of games with this deck. Can you please give me some support? I enjoy using this deck and dont want to stop playing the app because of a bug. Im seeing this…

Unable to create or edit deck ?
For the last 2 days I’ve tried to edit my deck and even create a new deck and I’m met with an endless “waiting for servers” loading message even though no servers outages have been reported. I seem to be the only one having this issue at the moment. I’ve done everything besides uninstalling and reinstalling including repairing game files.

Unable to add cards to deck during sideboarding
Today I played two matches of the last chance best of 3 qualifier. Match one I played on my PC and was able to sideboard. Match two I played on my android phone and was not able to add any cards to my deck during sideboarding. I could however remove them. This very directly lead to me losing the match

Deck Builder Doesn't Allow Card Incrementation
The deck builder doesn't allow cards to be incremented.
When selecting a card in the deck builder, a plus and minus icon shows up. Usually, if you have less then the maximum number of the card in your deck, you can press the plus button, and it will add a copy of the card to your deck. However, currently that icon does not work.
Steps to Replicate:
1. Log into Arena, and select the Decks tab
2. Select the + icon to create a new deck
3. Select any card in your collection to add it…5 votes -
Deck limit
Set a deck limit size or punish larger decks. Every other game is a deck with over 100 cards that NEVER bricks. The algorithm always allows for a balanced for OVERSIZED decks. Its not fun trying to beat an endless deck pool with an actual 60 standard deck. There's so little reports of this because most of your players abuse this mechanic in your game software. Its just unfun to play when every game again an OVERSIZED deck is an guaranteed loss

I am a new player and are therefore playing sparky challenge for the first time. I've beaten her a dozen or so times but for some reason I am stuck at 2/3 wins.

Malicious deck import can render deck selection permanently unusable.
This also applies to simply naming a deck the same way yourself, but don't do that! (Don't be like me lol)
Steps to reproduce:
- Create a decklist as shown in attachment Decklist.png
- Import while said decklist is in your clipboard
- Deck selection is now bugged and potentially unusable, has varying results.
- Logging out or rebooting does not fix the issue.Platform: Tested on both PC and Android.
Results: Deck selection has unpredictable behaviour, generally unusable.
Expected results: Either reject the imported name, or sanitize deck names.
Workarounds: Switching back and forth…

Unable to Sideboard
During best of three constructed in Standard, I'm completely unable to sideboard on either PC or iOS. Closing and restarting the client does nothing. When trying to add cards, they flicker, but are not added to the deck. using the +/- to add/remove additional copies doesn't work either and triggers and error when trying to submit.

Draft deck stuck on details
After drafting Avatar, I clicked on the deck details page to see what my average mana value is. From that screen, every time I try to exit back to deck building, it pops up the window to rename my deck. The only way to exit from deck construction is to go to another menu (ie home, decks, store, etc) and discard the changes that I made

Unable to sideboard in game 3 on mobile
In a ranked Bo3 match, between games 1 & 2, I was able to access my sideboard and make changes to my deck. In between games 2 & 3 however, when viewing my deck and sideboard, I could not add cards from my sideboard into my deck by tapping them; I was able to remove (or add additional copies) cards from my deck by using the + and - buttons, but could not replace them with cards that were in the sideboard and not the maindeck- obviously though, I could not register fewer cards than legal, so…
