Ink-eyes is able to target creatures that go to the graveyard at the same time that he deals damage. No player receives priority before the ability has to be put on the stack.

Steps to recreate
1.P1 Attacks with Ink-eyes and another creature
2.P2 Chump blocks the other creature
3.P1 Can now choose the chumping creature as a target for ink-eyes triggered ability even though no player has had priority.

When an opponent's creature enchanted by your Enthralling Hold is phased out, the creature incorrectly returns to play on the opponent's side of the battlefield during their turn. Your Aura remains phased out until your turn, at which point it goes to the graveyard.

By rule, since the control-change effect hasn't ended, so the creature should phase in on your turn (the controller's) with the Aura still attached.

I have Kess and As Foretold in play and am attempting to cast a card in my graveyard with Kess' ability and the mana replacement ability of As Foretold, but that is not an option on mtgo.

Auspicious Starrix only put one permanent onto the battlefield when i mutated my creatured even though my created had been mutated numerous times prior.

I cast fire prophecy and wanted to copy it with lutri and it resolved without giving me a chance

Mutate porcuparrot
Tap it to deal damage
Damage dealt is not correct

I lost a round of limited due to porcuparrot being bugged. The creature was mutated two times but when tapped was dealing 4 damage.

Lurrus does not trigger companion with expansion//explosion in the deck. Steps are:
1. Create a deck full of lands and 1 expansion//explosion with lurrus in the sideboard
2. Enter a game
3. Actual: Game resolves mulligans and turns start
4. Expected: Companion should trigger and allow the player to select a companion.

During my matches. I could not board cards in which caused me to lose

After being targeted by Merfolk Trickster's ETB effect, Ghitu Lavarunner's power does not shrink to 1. This happened to me twice in this game and resulted in two very bad blocks I was forced to make.

I've made this particular play many times, especially on Arena, and unless I am misremembering terribly, it resulted in the Trickster being able to profitably block and kill the Lavarunner.

I am open to being wrong because layers are complex, but I was 99.9% sure the Lavarunner should've shrunk.

doesnt let me use the ability of fiend artisan no matter how many mana i tap. my timing of the ability is correct but doesnt show the "done" button.

Unable to activate arbor elf during combat phase, so unable to pay Ghostly Prison cost.

Same as the subject. I clicked the "search your library prompt, and it skipped straight to finish resolving.

Had a hexproof 3/6 (Wingfold Pteron) that had 3 mutates on it, at the end of my op's Turn I flashed mutate a pouncing shoreshark onto the bird, drew a card for Dreamtail, targeted Luris with bounce and fetched a swamp for Greathorn, and this interaction killed my creature

sakashima in play copying a creature and being target by oko from the oponnent
When this happened MTGO made me choose a Sakashima to keep and even though I tried to click the creatures several times it didnt let me continue or cancel.

I played the card "Stalking Leonin" which has an ability that requires choosing an opponent. The ability did not allow me to choose an opponent correctly, and instead chose no one.

The game lets you know when your opponent is playing a deck that includes Davriel, Rogue Shadowmage, and Waste Not. (Game log on the beggining of each match "CreatedStepTrigger")

I had autoyielded Astrolabe and when I tryed to undo the yield it to win the game by clicking the button and on screen it did not do it and I drew my whole deck and died while I had lethal.
