Mid week magic deck building issue
I really like playing the mid-week magic events, and signed up and started this weeks Jump In on the start day yesterday. I picked Roku and Powerful like you normally would. Then, upon playing and drawing too many lands, I checked the decklist and 29 on the 40 cards in my deck are lands. This makes the deck unbearably unplayable, and I’m confident the powerful half of the deck is what bugged bugged as I have no green cards other than lands. I play primarily on my iPhone and signed up for this event before whatever update you pushed…

Red/Blue Deck Invalid with no Warnings or indication of why
(PC, Epic Games Store)
I was trying to play Alchemy, (tried Ranked and Unranked) with a newly made deck and it consistently returns with a "Invalid Deck: Deck validation failed." message after I select "Play".
No further information as to why the error is occurring is displayed, preventing me from resolving the issue on my own.I have tried removing cards one by one and playing, then adding them back when the error still occurred to narrow down the cause of the issue, but was unable to play, leading me to believe it's not an issue of a single…

Bug - Endless "Waiting for the server" loading screen on deck builder
To encounter this bug, I just entered the deck builder. Any limited event and the collection deck builder all produce the same issue. I tried this on PC Steam and PC standalone install. When entering deck builder I just get an endless loading screen. I am unable to edit my decks. This error doesn't happen on another computer in the same local network, however reinstalling the game did not help on my PC. I tried port forwarding ports 30010, 30003, and flushing DNS cache, as well as trying alternate DNS servers. I also tried a clean reinstall using Revo…

Deck testing against bots
It'd be awesome if you could test decks that you dont have all of the cards for at least against a bot. That way you'd know if your deck idea would even work.

Raise maximum deck size
Can we raise the maximum deck size in MTG Arena?
I totally understand there are technical concerns, but I’d love the option to play decks larger than 250 cards. I know it’s not optimal for competitive play, and some players might not like it — but I really enjoy building huge, weird decks, and the current cap can feel a bit arbitrary.
I’m aware of the old shuffling guideline ("a player must be able to shuffle their deck themselves in a reasonable amount of time"), but we’re using digital tools now.
It wouldn’t affect competitive play, since those …
