I cast Kotose, the Silent Spider choosing to exile Kumano Faces Kakkazan.
I play Kumano Faces Kakkazan.
When the 3rd lore counter is put on it, the saga is supposed to be exiled and returned to the battlefield transformed as Etching of Kumano under my control. However, it went to my opponent's control.

magic online would not let me sac a fetchland in response to a spell pierce. I was then unable to pay for spell pierce even thou I had 2 lands in play causing me to lose

Valki exiled Graveyard Trespasser from opponent's hand. Used Valki ability to become a copy of Graveyard Trespasser and attacked, exile Tenacious Underdog from the opponent's graveyard. Later Valki died and Tenacious Underdog was returned to the graveyard, erroneously linked to the Valki ETB ability.

Everytime I tried to cast Rift Bolt from it's suspended state, the client wouldn't let me. It would say to "Click the card to cast it" but when I click the card on the stack, all it would do is give me the different yielding options for the card. No matter where or how I clicked the card, it wouldn't let me cast it, leaving me in a soft lock on my match, unable to take any actions.

Spellweaver helix won't create a copy with 2 exiled cards of the same name:

During a 4 player edh game, i cast spellweaver helix exiling 2 dragon's approach. I then cast another dragon's approach, Spellweaver helix triggers but it never places a copy of dragon's approach on the stack as i'd expect.

After verifying with the ask the judges group on facebook, and the rulings on gatherer, i'm 100% positive the spell should have copied.

I linked the ruling on gatherer.

Round 1, Game 1: I controlled a Chandra, Torch of Defiance, and my opponent used Wild Slash to deal the Chandra lethal damage while controlling Etching of Kumano. I believe that the creature's ability, which is supposed to cause creatures dealt damage to be exiled, wrongly applied to my planeswalker. The Chandra was exiled, which caused me to not have enough cards in my graveyard to escape Kroxa, Titan of Death's Hunger, thereby affecting the outcome of the game.

Abandoned Sarcophagus exiles cards when you cycle them, instead of letting them go to the yard. It specifically says they go to the yard if cycled.

Undercover operative copied a freelance muscle and got a shield counter

opponent prizefights their 7/7 muscle verse my 4/4 muscle with a shield and mine dies

Attempted to use Shigeki's Channel ability to retrieve X non-legendary cards from the graveyard on main phase, but was unable to while i had the appropriate mana to do so. I had used his first ability to put those cards into my graveyard with the intention to get them back.

Hey there,

I report a bug that occurs in my Pioneer open constructed games.

Dread Presence's trigger doesn't work well. It seems like it works like a "hasn't been choose" choice mode.
I mean when Dread is in play, the first swamp let me choose one of the two options, the second swamp triggers automatically the option that hasn't been choosen yet, and from the third swamp no trigger happens anymore.
This is a bug that happens since 2 or 3 days consistently.
Thank you in advance.

Situation
1.I have Wiretapping on my field
2.End step of my opponent, I activate Demon's Due
3. Actual : After it resolves, Wiretapping forcedly activates, and the mandatory trigger forces me to draw my whole deck
4. Expected : Wiretapping is only supposed to trigger once, and only during my draw step

My opponent used their Scheming Fence to Sacrifice MY citizen made from Citizen's crowbar to destroy my citizen crowbar.

The card was Life of Toshiro Umezawa. The Black Saga for 2 Mana. I couldn't click the same Mode again.

I cast 3 spells in a single turn and the phoenixes don't revive from the graveyard

Any time Faithbound Judge or Sinner's Judgment triggers, the game gives an error message and crashes. This immediately makes it impossible to continue playing the match, and seems to consistently occur every time the trigger resolves.

I cast Sphere of Annihilation with 6 counters on it. I allowed a turn to pass and the sphere triggered on my next upkeep. the sphere exiled itself, but the other permanents it should exile with the sphere, did not get exiled. this bug cost me the match. both my opponent and myself were baffled by the failure of the sphere to trigger correctly.

1. I put Kaya's Ghostform on my Perilous Myr.

3. Perilous Myr's trigger goes off but Kaya's Ghostform doesn't trigger.

4. Kaya's Ghostform successfully triggers and brings back the Perilous Myr.

Turn 8
Opponent blocks [Spring-Leaf Avenger] with [Atsushi, the Blazing Sky] that has [Leech Gauntlet] attached to it. I cast [Return to Action] and target [Spring-Leaf Avenger] in response. Both creatures die however [Spring-Leaf Avenger] gets exiled instead of returning to the battlefield.
