At the beginning of game two after i played my first land Shelldock Isle and was resolving the Hideaway trigger the game startet again. My Opponent and i both got a new hand of seven cards.
Each turn after that the client went directly to the cleanup step and made us discard a card due to maximum hand size.

I was playing when he played a card of Strixhaven (Expressive Iteration). Game broke. I saw all the game again since t1, like when you review a past game on Game Historial. Then the game restarted

When a player is disconnected during gameplay, and often leads to being dropped from their event.

The game replayed itself then started match again with new hands. Also there was no priority neither for me or my opponent.

When lag causes a misclick or skipped action. The user isn't disconnected from the client though.

mid game it restarted, after the restart the game is just skipping through turns going immediately to discard

Cast Academic Dispute. It makes the creature have to block. Then it asks if you want to "use the ability." So I hit no, assuming it was asking about reach, because not a single other Learn card has asked me that question. Then it didn't let me Learn, and it also didn't prompt me about giving reach. So I assume, if I hit "yes" that it would either give reach and let me learn together as one option, or simply never have the option of giving reach.

1. I played Doomsday.
2. Resolved Doomsday and chose 5 cards from my library and graveyard.
3. Opened Temporary Zone Window, i executed Undo.
4. Magic Online rolled back and couldn't progress the game.

My opponent use the ability of Sylvan Library, but when you click on "Undo" the game is bugged and restart. Please fix this bug!

watch replay. Turn 8 of opponent, my skyclave sentinel was given indistructible with oblivion's hunger and blocked his deathtouch enabled expedition skulker, but it still died at the end of the turn. Not only did this bug cost me the game, but unfortunately also my 8th competitive trophy to unlock the ZNR mythic avatar.

Unsure if avatar can be released to me via back end, but if not, requesting full reimbursement for the entry fee. will not accept game reset as draft queue ends in 12ish hours from now and I will not be able to play another game

hey, i just played my game 3 vs matti. i attacked with icehide troll, he blocked, i activated the ability to make it indestructible. Then used my fightspell to kill my opponents creature and passed the turn. End of turn my troll randomly died to nothing.
Even opponent didnt see a reason for that.

Have an opponents creature cast with effect Dauthi Voidwalker die while you control another copy of Dauthi Voidwalker. I did this and my opponents Lurrus when to the graveyard instead of being exiled with a counter.

Used blizzard brawl with more than 3 snow permanents against a deathtouch creature.

There seems to be a bug where using blizzard brawl against a deathtouch creature and it dies at the end of turn

Opponent casts Prismari command choosing the 2 modes of deal 2 to any target, and target player draws 2 cards then discards 2. Opponent targeted me with the deal 2 damage, and himself with the draw 2 discard 2. I took 2 damage, opponent drew 2 cards, but I was forced to discard two cards.

When the User Experience or User Interface is involved in an issue. Generally not a technical bug, but where the client could be improved to help reduce confusion.

Attacking with a creature with ranger class at level 2 or higher will sometimes cause the current game to restart.

I was 2-0 after 2 first matches, match 3 was 1-1 and i was in the lead in game 3.
I had Mandrills in play, Oko in hand, opponent was hellbent and casts oko from from graveyard. In my tur i resolve Oko, and elk the uro, no block. Turn after opponent attack oko with Uro like I expected, but here is the bug: The Uro aka Elk triggers on attack oppent draws and gain life. Draws new creature, and the game runs away for him, my loosing my potential 3 of 5 matches.

1. Have 2 sorcery cards in your graveyard and nothing else
2. Click on 'Reconstruct History' from your hand to try to cast it
3. Notice bug (see attached screenshot)

I did have legal targets in my graveyard, but whenever I'd try to cast Reconstruct History, it wouldn't let me target them. Clicking 'OK' didn't do anything - the same message displayed. All I could do was click 'Cancel'. I tried casting it multiple times and no change
