Just happened in a quick draft I did

Same here

I wanted to cast Feed the cauldron during my 1st main phase and the timer goes to zero so it passed to the declare attack phase. Feed the cauldron was then out of my hand and not casted. It was floating around for the rest of the game causing me not to see the whole battlefield. Also I almost lost the game because I was one card down. Poor game experience...All is ont the secreenshot. The bug was around 00:15 pm UTC.

I had to concede the match. During the 2nd try the match was also bugged - however, i was able to win the game as the creature that was usable was strong enough to survive/deal dmg while the other create remained unplayable beneath some cards my opponent played.
FYI it was the thrid boss playing blue.

Tutorial got bugged. Cards that were played did not go into graveyard but remained in the air/over the battlefield. At some point i could not select cards that i played before because they were "under" other cards.

Thanks!

phantom cards still showing and the animation got stuck, it doesnt allow me to finish the game

Cards dont go to the play mat, hard to play when you can't see anything

During merfolk tutorial mission, cards stopped playing and simply levitated in the air. Attached is a log report. Please look into this, as new players shouldn't be confronted with game breaking bugs this early on, thank you.

I cast a drakuseth and it resolved and stayed on the stack and broke the counters in the game

Cards don't disappear after being played.

They block the view of other cards.

Cards remain "Displayed" after being played from their owner's hands... indefinitely.

Cards are sticking to the screen on the side and in the middle of the field and not going away after being played. Also not being displayed properly on the battlefield as well.

The Vendillion Clique had been on the stack for the majority of the game after I had attempted to cast it. Its failure to resolve cost me the match.

A spell was stuck on the stack for the remainder of the game after I tried to cast it. Losing the card cost me the match.

I play a card and the card image remains in the stack area and does not appear on the battlefield or graveyard. At the same time, the images of permanents on the battlefield "freeze" too. Lands do tap for mana, creatures do attack and die. But I dont see these changes. I cast a planeswalker, his image is in the stack area overlayed by other images already stuck there. If i click on the planeswalker image on the stack, I get to activate its abilities...

This issue happend from time to time in a small scale before the 18.7.2023 update, but right after the update it happened ca. every second game and lasted for several turns until I lost, because I could not use my cards, or until it suddenly fixed itself.

During a game, the screen turned dark and 'waiting for server' appeared with a spinning circle, however the game continued to play as normal in the background (with opponent making actions and then my cards highlighting when priority passed to me). After timing out on my opponents turn, it passed to my turn and my hand became highlighted, and the 'End Turn button appeared, however the screen was still dark with 'Waiting for Server and I was unable to click on anything. I closed the program and restarted. By the time I got back in it was my opponents turn and after they finished their turn priority passed back to me. I attempted to cast 2 spells. The first one (Ichor Drinker) went on the stack and remained there without hitting the battlefield. I was unable to take any other actions and watched as my timer burned down. Eventually the cards in my hand became highlighted again and I was able to attempt to cast a second spell (Flitting Geurilla). This spell appeared to go onto the stack above Ichor Drinker, but then immediately came off the stack and onto the battlefield. I was not able to interact with the Ichor Drinker on the stack at all and my timer ran out. The Ichor Drinker remained on the stack for the rest of the game, screenshot attached showing the Ichor Drinker on the stack during my opponents turn.

I attempted to cast sever the bloodline (sorcery) as the rope was burning (main phase 1), however the spell got stuck on the stack and was never cast. I was instead moved to combat. For the remaining of the game I was unable to cast the spell. Game was a SIR premium draft played on iOS. Resulted in an unplayable game as I effectively mulligan and the spell blocked half of the screen.

I did not find a work around to fix this while in game.
