Told I have too many of a "you may run any number" cards
Playing on PC. Building a brawl deck with cards that allow an unlimited number (ie relentless rats, hare apparent). I get a notification when building that I have too many of a card. Further, all decks I already had that run those cards have been deleted.

Foundations Decks have missing cards
I just updated the game today and got the New Player Decks on my Inbox, but I didn't get all the copies of the cards on the decks and as such some have missing cards. For example the Path of Power deck is missing Temple of Abandon

Duplicate protection bug
There is an error where rares on the bonus sheet for Through The Omenpath were not protected against duplicates. This causes rares to be gemmed even though there are still some remaining.
Similarly, the Stellar Sights on the bonus sheet for Edge of Eternities also have no protection against duplicates.
This is a bug that causes losses to players, so please fix it immediately.
Previous sets properly had duplicate protection on the bonus sheets.

Rat colony says invalid deck if I use 6 or more of the style cards, but works ok with default cards.
When I go to use the style I brought for Rat colony after reading the Dev diary about the card style changes I discovered an issue when I went to use the style in my decks when I hit 6 or more cards, I get an error saying that it contains cards not in my collection, and then the deck page says I need to have 3 more common wildcards to finish it, but it also does not give me the option to use them to stop the error, so the only way to make the deck valid is to…

Set Completionist II
The achievement for 4x copies is not giving credit for completing the Final Fantasy set. I have Set completionist I, which I got for the Final Fantasy set but the second will not credit. I have spent multiple rares trying to complete. I pulled up Untapped to see cards and the only thing that I notice is not getting credit for having all 4 of Cid, Timeless Artificer. I have every artwork but Untapped shows only having one of each. I am unable to craft the remaining ones Untapped shows as missing since Arena shows I have all 4 of…

"Anti" theme/ability?? new idea
Creatures with "Anti" anything ability would cancel out the other creatures ability. Anti trample creature would CANCEL the creatures attacking trample ability if the creature blocking had "anti" that. First strike, any color, creature, spell, enchantment, "anti" ability?? A spell with "anti flying' put on a creature would ground it. Apply "Anti" to things. Is "Rampage" or "Banding" going to come back? Banding is just Reverse trample basically. the ability to assign damage to your creatures.

Sideboard Size Problem
Game will not allow the creation of a deck with between 8-15 cards in the sideboard. The error message reads "Decks cannot have more than 15 cards in the sideboard" when there are not more than 15 cards there. This bug prevents me from playing with a full sideboard with my existing decks in bo3 as well.

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…

Brindle Boar added for Pioneer
While the majority of meta cards are in the Pioneer card pool, there are some important cards that would enable other decks to compete at a tier level. Brindle Boar is an excellent example of this. I've personally topped and won multiple Pioneer RCQ's with Insidious Roots decks, but the deck can struggle against hyper aggro, i.e. Monstrous Rage decks. There's no card in the available card pool that's even remotely on the same power level as Brindle Boar is at negating these issues. Brindle Boar's activated ability paired with Soul Cauldron is too powerful to replicate.

sideboard

Can't Edit Decks
I'm unable to edit my decks. It says that no more than 15 cards can be in the sideboard. My main standard deck only has 13 cards in the sideboard and I tried adding 2 more card to make it 15 but it said I couldn't add those cards because it would be over 15 cards. Then when I tried to remake the deck new the same pop-up happened when I tried to finish making the deck. I'm also unable to change out cards for other cards in the sideboard or maindeck, the same "15 cards in your sideboard" message…
