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.

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

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

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.

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.

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 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

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.

Animating Artifacts with Karn, the Great Creator's +1 ability does not give the correct stats to the creature artifact.

1. Have karn, TGC and any non-creature artifact with CMC /= 1.
2. Use karn, TGC +1 ability to turn it into a creature.
3. Expected: The artifact becomes a artifact creature with power and toughness equal to its CMC.
4. Actual: The artifact becomes a artifact creature with power and toughness equal to 1.

Parallax Wave fading doesnt work, the enchantment is permanent

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.

1. I cast primeval titan
2. Opponent cast Dress down in response
3. Dress down resolves, they draw a card
4. Primeval titan resolves
5. Actual: Primeval titan etb triggers
6. Expected: Primeval titan shouldn't have an ability

Attack with Hunter Sliver and/or other Slivers with Provoke, the provoke trigger is not working.

Actual: It doesn’t trigger provoke
Expected: They should all have Provoke

The card Brass Knuckles is bugged. Even if u leave the opponent with 1 equipment, the attached creature still has doble strike. I destroy the equipment 2 times, in g2 and g3, but it still mantein the ability that requires control 2 equipment.

A creature died and I didn't get the trigger off of Morbid Opportunist.

Note ability:
Whenever one or more other creatures die, draw a card. This ability triggers only once each turn.

Regent's Authority doesn't add the +1/+1 counter

It was cast during combat on a legendary creature.
The creature gained +2/+2 but not +1/+1 and a +1/+1 counter

Katilda's ability is not working correctly. instead of allowing you to tap humans for mana it is instead acting as if it adds flavor text. I have had multiple turns where I could have done many things on my turn (Including using the other ability) but instead it is just flavor text that does not work

I cast Tamiyo's Compleation and targeted The Wanderer
Even though I can target a Planeswalker with it, it crashed MTGO
I keep logging in and it keeps booting me, I'm stuck

Ob Nixilis, the Adversary + Esika's Chariot - copying the Ob token w/ Chariot doesnt creat another Ob token
