Deck builder Sideboard cant count.
In deckbuilder, if sideboard has 8 or more cards the client will not save the deck and reports that “a deck can not gave more than 15 cards in the sideboard”. There were 8.
I tried with other cards and other sideboard sizes. 7 or less is fine. 8-15 is bugged to automatically think its more than 15.
I saved the deck with a small sideboard then reopened the deck and still encountered the bug.13 votes -
Kotis
Kotis, The Fangkeeper ability to cast from exile is currently bugged (2025-09-17). In the last 3 matches I had I was able to attack my opponent at least 3-4 times and only one of them did the window open where I could see the cards that were exiled and if they qualified, cast them. The only visual I see, is an orange 'resolve' button and on the first instance, I just clicked it thinking it was a new way to see the exiled cards, but it did not. However, there is a workaround that I found. After hitting the opponent, I could click on their exile pile and see the cards that way, and be able to cast qualified cards that way. However, this is not intuitive and not the behavior it used to work as.

Arena Anthology cards missing
Some cards both of the Arena Anthology sets are missing in the collections tab as well as when trying to build a deck. The cards I've personally noticed that are missing are all of the signets as well as mother of runes. I don't know if there are any more.

Back button in Deck Info screen (premier draft) is non-functional
When in the Deck Info screen within premier draft deck building , there’s a glitch where the back button does not go back to the Deck Builder screen. I’m on iPhone iOS 18.6.2. This happens consistently to me since the Avatar release. The only way to get out of the Deck Info screens is to exit the draft and restart the “Build Deck”.

Pentad Prism with Colorless Mana Floating
Pentad Prism cannot be cast for Sunburst=2 if you have a colorless mana floating that you can't undo (e.g. mana from Sol Ring, Mana Crypt, Mishra's Workshop, etc., where you already spent one of that mana on another spell), even if you also have colored mana floating. When you go to cast the Prism, the game autopays the colorless mana, and undoing that payment of colorless mana also undoes the casting of Prism. This was in full control mode, and with auto-tapper off.
This is also an important, potentially game-losing issue - I lost a game due to being unable to use Prism to filter my colored mana into a different color to cast a Minsc and Boo pre-combat.
I propose that not only should Sunburst cards have special handling preventing mana (especially colorless mana) from being automatically paid, but that a single press of the undo button (Z) should only undo mana payments, and should require a second press to undo the casting of the card itself.
Lastly, I have not checked, but there is a chance that this bug also applies to Converge and Adamant cards, so that is likely also worth looking at. (Or alternatively, if Converge and Adamant cards already have special handling, maybe that can be applied to Sunburst?)

Sanctuary Warden No Choice
When Sanctuary Warden enters the battlefield or attacks and is the only creature or planeswalker with counters on the battlefield, one is automatically removed instead of giving me the option to choose to remove or not (as per the "may" on the card.) I'm playing on a Windows.

Bug: Cannot properly cast cards from exile after Sept 16 update
Cards with cascade or the ability to cast a card from exile (like Etali, Primal Conqueror) do not properly allow cards to be cast from exile. There is simply a resolve button without the option to cast the cards.

Kotis The Fangkeeper
Kotis The Fangkeepr’s ability doesn’t properly trigger after latest update on mobile. When dealing combat damage as required, X amount of spells are exiled as they should be. However, instead of pulling up the list of castable spells as the game should, it fools you with a fake resolve message. If you click resolve, you skip your turn without casting any of the free spells because it never shows the option. The only way around this is to IGNORE the resolve button and click on the opponent’s exile pile and manually cast spells from there. Emphasis on IGNORE THE RESOLVE BUTTON. Hopefully this will get fixed soon.

Modern Horizon Japanese Booster box event
Hi ! I just bought for 8000 gems a run with the modern horizon 3 event today. And I can only see 7 of my cards (I'm not speaking about the rares opened in the begining). I tried all the filters and I already did a lot of sealed on mtg arena so it's not a classic miss of filters. I just can't make a deck at all as I don't have any visible cards but the 7 I just told you about. Is anyone experiencing that ?
