Maximum deck limit On MTG Arena
I Have been coming across a lot of decks that have over 150 cards in the deck and usually surpass the 200 card deck count on MTG Arena.
These games are never fun due to long drawn out games and for people that enjoy playing Mill decks the Mill deck will lose by default because the card value of milling is well balanced to achieve success when the decks have a quarter of a thousand cards in the library. Second; There are several answers in the game to either win the game due to not having cards in the library…

"Show and Tell"
Ok, the card "Show and Tell" and the ability to put a card into play with NO COST, is broken. I don't usually complain. Just play through it. But, in ALL of Magic's past, Any card that does something for free... much less InTo Play.. oh come on. Broken and abusable. Who came up with that card? Let me guess they came up with another 10 over powered "cool" cards. They don't "get it', the true game of Magic. If I am correct with my guess. sadly change their ways, or fired. Not the right fit for the job. NO…

Second Day of Sideboard issues
As of today, 07/11/2025 this is the second day in a row that MTGA will not let me put more than 7 cards in my sideboard. This is across different new decks, and after multiple game and PC restarts, as well as game updates. I will post screen shots, but I am unable to compete in best of 3 without a proper sideboard and the opportunity cost this is having on me is immense. I am attending SCG orlando in 7 weeks and I cannot properly test. The error message "This deck cannot have more than 15 cards in sideboard"…

Sideboarding problem (standard format)
The sideboard is ONLY allowing 7 cards instead 15 in standard format. Problem seems part of recent REPROGRAMMING. The sideboard says invalid with only 8 or more cards.

Brawl deck not working
I can't play 2 decks as error states that there are too many cards of the same name in a deck. 1 deck has Nazguls and the other has Hare Apparents. Shouldn't this still work?

The 15 card sideboard warning prevent editing or building sideboard. Great dissatisfier and devalues this product.
I suggest the sideboard problem be fixed. Screen says I have more than 15 cards. This is not true. It does not allow me to edit my sideboards. Already restarted my computer and repaired game files.

Deck
I have been playing a brawl deck for months that has hare apparent as the main theme producing many tokens. Hare apparent states that a deck can have any number of it. Today I updated the app and it somehow now invalid saying there's too many copies. I also attempted to delete the deck and rebuild it from scratch as per troubleshooting and it did not work. I am using an android phone to play. Any work around for this? I noticed a few others with bugs of the same type, such as running into this error but with nazguls,…

Can't edit Decks
A message that says" You can't save/edit this deck because it exceeds the maximum of 15 cards in your sideboard" keeps popping up whenever I try to add cards or change cards in my decks or sideboards. This is making it impossible to change up my decks and I also can't make any new decks either without getting the same pop-up message about the 15 cards.
