Invalid deck error
After the newest update, my Standard deck is invalid due to a side board error. It says I can't have more than 15 side board cards but you can see in the image that it is 60/15.

Companion list unavailable
After the last update (2026.54.40.5293.1221064), I'm suddenly unable to select a companion for my decks. The list of companions is blank (although I have like 12+ unlocked companions), only the preselected companion is visible. I'm playing on Android app.
Please fix this asap.6 votes -
Cannot have more then one copy, Brawl bug.
I have five decks that are no longer valid in Friendly Brawl because they contain multiple copies of cards that should allow it. Eg: Rat Colony, Persistent Petitioners, ***** Against Humanity, Nazgul, Hare Apparent.

Deck Building Issue
Is anyone else on IOS having the issue in deckbuilding during a draft where the back button in this screen does not work? You have to cancel deck building (and all current deck building changes) to return to the draft deck.

Brawl states I have too may copies of a card that states i can have any number of copies
I have cid timeless artificer which states I can have as many copies in a deck as I want, but when I try to play it it gives an error that I have too many copies. If I remove them all and replace them with something like islands its fine, but if I add even one extra it gives me that error

Set Completionist II
Set Completionist II not giving me credit for completing the Final Fantasy set. Please fix this, I spent so many Rares and Mythics on this. My only thought is FF of the Ages is also required, and if so, then its very misleading... Yes, I have 4x of every card in the Final Fantasy set, but not FF Of the Ages.

Avatar Jump-In packs clearly not correct
I started an Avatar jump in and selected firebending and powerful as my packs. It came out with only 13 non-land cards. Clearly one or both of these packs did not populate the correct cards.

Brawl not accepting Hare Apparents?
Just got the new update, it cancelled out my Aerith Brawl deck initially for 19 cards not accepted. Built a new one thinking it might be because of the rotation of sets. Turns out, it was an issue of there being more of the same card in the deck (Hare Apparent) although the function of Hare Apparent allows for more than one of them in a deck. The deck had worked before the updates. What's changed?
