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

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…

Received 20 gems in rare slot of a pack despite NOT having all of the rares from that set.
I bought a pack of Foundations and it gave me 20 gems instead of a rare, with the mouseover text "You have collected all of the rares from this set". Except I haven't collected all of the rares. Please see attached images and log file. Could you please give rare wildcards instead of gems? This 20 gems instead of a wildcard feels like I'm being cheated, and lord knows I've spent enough money on this game.
Thank you for your consideration,

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…

Avatar Jump In hides feature cards from collection
Avatar Jump In selection hides the featured cards from my collection. If Aang is the featured card, he doesn’t show in my collection unless I add the deck directly from Jump In

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
When building a BO3 deck I was creating my sideboard of 15 cards.
But I am unable to save the deck because the game says I have more then 15 cards in my sideboard. even though I have the maximum amount of cards in the side board.This problem doesn't happen with 7 cards in sideboard .
