1. It is night and Leeching Lurker is on the battlefield
2. Cast 2 spells on your turn so it becomes day next turn(search party captain and curse of leeches)
3. Neither player has hexproof/shroud etc.
4. Actual: Upon Leeching Lurker's transformation it goes to the graveyard
5. Expected: I am given the choice to attach Curse of Leeches to target player, and the enchantment remains in play.

I attacked with Gallia and two other creatures, after hitting "yes" I discarded a card at random and drew 0 cards. In two other matches, Gallia discarded a card at random without drawing any cards

wiretapping, new card from New Capenna is bugged. I was playing against my opponent Sargo Vito8 on Magic the Gathering Online in a Draft Queue. This was game 1. He drew a card and the effect went onto the stack, but it repeatedly carried on until he would otherwise draw his whole deck and he couldnt end the loop.
As a result of this loop he lost the game

After the 4/27/22 downtime, permanents with multiple modes on a triggered ability do not let you select a single mode more than once.

I can't play cards exiled by Containment Construct ability.

After targeting a Riverwheel Aerialists with a Rite of the Serpent in a Khans of Tarkir phantom flashback draft league, the game bugged out and restarted

You can't cast it unless you have a Dragon to reveal, or a Dragon on the battlefield. You can't cast it to deal 3 to a target.

My opponent only had Raff in play, cast Artillery Blast and was prompted to tap Raff to draw a card. Raff's ability only should trigger when tapping TWO creatures but my opponent drew off of ONLY Raff.

when you attack with moon-circuit hacker and you say "no" to draw a card, you still discard.

Whenever a creature attacks, Anointer of Valor's ability triggers but instead of the counters being placed on the attacking creature all counters get placed onto Anointer of Valor instead. This just happened with the 2/9/2022 update.

During a Challenge match I discarded 2 cards through the Fable of the mirror breaker card and didn't draw 2 cards, some bug happened

when greater gargadon is suspended,gargadon can reduce time counter by sacrifice.And normally,time counter get 0,gargadon can cast.
but actually,gargadon can't cast.The window for cast don't appeared.I think its bug.

Actual: after casting Igneous Elemental for its discounted cost because I had a land in the graveyard, it resolving and me targeting their marauding blight priest it gave the opponent the choice to accept their creature being dealt the damage or not.

Expected: their creature should have taken 2 damage, they should not have been presented the choice to accept the damage or not to.

Issue happened in Match # 249166573 Game 799729612, the opponent assisted trouble shooting the issue and it was happening each time I cast an Igneous Elemental.

The card Fires of Victory from Dominaria United deals no damage to the targeted creature or planeswalker.

The card Fires of Victory was cast during combat on a creature with no damage assigned, so that, if functioning, the creature would have then died during combat.

Actual: No damage is assigned. The creature survives combat.

Expected: Damage is assigned equal to the number of cards in the controller of the spell's hand. The creature dies after combat damage is assigned.

Selecting See the Truth with Founding the third path's third chapter only let me chose 1 card, not all 3.

Adeline resplendant Cathar doesn't let you choose if you want to attack a planeswalker or the player with the token she creates

1) Attack with any creature while Adeline is on the board.
2) Adeline triggers but there is no prompt like you would expect on her text.
3) The token is created, attacking the opposing player whether or not you attacked a planeswalker or would like it to be attacking a planeswalker.

Turn 11
Opponent targets Land with creature type added (Basic Swamp) from Harmonious Emergence with a removal card (Twisted Embrace). Swamp stays a creature, gains indestructible, and Harmonious Emergence doesn't get sacrificed.

When I played a faerie miscreant it's trigger activated and I drew a card even with it being the only card named Faerie Miscreant on the field.

I have a leyline of the void out and opponent cast Yawgmoth, Thran Physician. I cast indomitable creativity on his Yawgmoth and it did not destroy the Yawgmoth but it got him a Young Wolf instead as well.

I used Karn and +ed on my skysovreign, it made a 1/1 creature where it should have made a 5/5, this also happened in the previous match with a different artifact
