Tinybones, Trinket Thief is bugged. It is triggering off the player who owns it discarding cards rather than the opponent discarding cards.

Event#12168868 Match#230372493

Wild Cards are not processing. It freezes the Wild Card button after clicking, and looks like maybe it did create a wild card when you look at the wild card screen. However, the animation for creating the wild card never plays & I do lose my wild card. But, the new card is not in my inventory.

it triggered when i attacked a different player all together and it triggerd and killed my creature when i wasnt even attacking the player who played it

In match 230548503 one user failed to select a card for intuition and it gave the opponent all three cards.

A player is able to use a card's suspend effect (i.e. Ancestral Vision) after using their Teferi's +1 Planeswalker ability.

EDIT: Your report page is bugged and doesn't give me the option to pick the category game play report bug. See Screenshot.

I also wanted to report on the card. Offspring's revenge on a possible bug.

Opponent has offspring's Revenge with a lot of creatures in their graveyard.

Like a drakuseth dragon. I used a Elspeth nightmare to eventually empty their graveyard. The opponent is still able to access their grave yard exile to use their offspring's Revenge. Is this bugged? They didn't target any card from their graveyard. There's nothing there.

Gideon Jura took damage from a spell (in this case searing spear) while his 0 ability was on the stack. This removed 3 loyalty counters from him, bringing him to 4. After the ability resolved, opponent cast dismember on the Gideon, which appeared to have 3 damage marked on it (from the searing spear) and thus died. I believe it shouldn't have had the three damage marked on it since it was a planeswalker (and not yet a creature) at the time when the damage was taken.

Since you guys changed the rule of COMPANION,there seems to be a bug in the B03 system for the draft game.

I used a companion in one of the draft game,and on the B02 game,I found that I can not replace card from my sideboard.Even I replaced some card from the sideboard into my deck,in B02 game the deck still remain the same as my B01 deck.And I could only make the replacement in B03 game.As the result,I only made one win in the draft.

Opponent not dropped after inactive for designated amount of time.

Certain random cards (Cleanse, Crusade, Distant Memories specifically) are suddenly showing up as Banned in every format, including Freeform. This has obviated a substantial percentage of my decks without warning.
Firedrake on MTGO

Deck editor shows Crusade as "not legal in this deck format." But it's totally legal... and I've even played with this deck before.

I had Trinisphere in play and the client was not allowing me to cast Chalice of the Void for X =1 and pay the aditional cost. It kept just allowing 'Cancel' or 'Adjust' and Never 'Done'. It would only allow adjustments to X = 2 or greater.

I can't see most of the cards in my collection as of today. I know I still have them because I can play decks with the cards I can't see, but I can't build new decks.

if a creature entered the battlefield under my control, it should be returned to my control when the player who controls it dies

example...
bazaar trader declared as blocker..
bazaar trader uses ability to change control and is therefore removed form combat,
new owner of bazaar trader loses game...
bug: bazaar trader does not return to my control.

for reference other cards like immortal coil will return to my control after i give them to the opponent and they lose.

Starfield of nyx triggers and returns history of benalia and history of benalia automatically triggers the saga twice and ticks it up to two counters and players are abusing it.

Island Sanctuary was bugged for my latest game. It allowed non flying non islandwalk creatures to attack me when I had skipped my draw step. Match #230308247 Game #724592034.
