TextMeshPro abuse with WOTC DisplayName = 100% win rate against Desktop and iPad opponents
MTG Arena does not sanitize user Display Names. A nefarious user can create a Display Name with TextMeshPro markup to have an unfair advantage (100% win rate) against players using Desktop and iPads. This can cause frustration with other gamers and lead to loss of revenue if paying customers decide to leave the platform.
However, in performing this abuse, a player has lost a lot of game functionality themselves. For example, they must also play on mobile only or play with a modified client on an affected device.
It is easy for any user to create a new account (no email verification before you can play), a very easy exploit for users to abuse.
Due to the reasons listed above, I’d classify this as a low (maybe medium) risk/issue.
Proof of Concept / Reproduction steps:
Register a new WOTC account at: https://myaccounts.wizards.com/register
Create a character Display Name with TextMeshPro size markup and >= 4 unicode block elements:
<size=9999>████[photo 1 - displayname]
Upon playing, you will notice match screens will show a large white box (the name).
Example photo, me playing a game against Sparky:
[photo 2 - affected game]
I have also confirmed a real opponent sees the same thing on Desktop when battling this user.
I did not test on an iPad myself, however, I believe they are affected as online videos of iPad use (example link: https://www.youtube.com/watch?v=ZewSXhYKRB8) show names displayed on screen, unlike mobile phones which are not affected (tested on Android).
[photo 3 - iPad client YouTube video]
Mobile devices are unaffected as Display Names are not shown at all times during the match. The user abusing this will have to use a mobile device (or an otherwise patched client) to get past the tutorial and play human opponents.
Remediation:
Sanitize user input before passing to [TextMeshPro] sinks and/or restrict WOTC display name character sets.

Bug: Cannot counter spell in TLA Omniscience quick draft
Cannot counter spell in TLA Omniscience quick draft
My opponent could cast spells without me having the chance to counter them using Sokka's Haiku in my hand (for 0 Mana).
Happened consistently. Yet to find out if other counter spells are affected as well.

Improve the game for Foldable Phones
Please fix the game for foldable phones with square-ish aspect ratios... since this is made for mobile phones, it doesnt detect that foldable phones have a bigger screen with a different aspect ratio... so what happens is that the buttons are way overblown, you cant even tap the buttons because it's being blocked by the Stack on the right side.... etc. Deck building is also so bad. Please fix this.

Rottenmouth Viper incorrectly shows highlight indicating it is able to be cast.
In this image you can see that the Rottenmouth Viper (in hand, far right) is highlighted as if it can be cast. I suspect this is due to the fact that this treasure token is being double counted as both a mana source AND a permanent that can be sacrificed to reduce the cost. (Potentially because of the Name of the card being atypical)

Title: Deck Format Dropdown Is Obscured / Unclickable in Deck Details (Alchemy)
When viewing Deck Details, the dropdown used to change the deck format (e.g. Alchemy, Standard, Explorer) is partially or fully hidden behind the UI panel below it, making it impossible to select a different format.
In the screenshot attached, the dropdown is visually present but overlaps with the deck statistics panel, blocking interaction. This forces players to recreate the deck in another format instead of switching formats as intended.

Ajani Outland Chaperone - Warning: Please take a different action or the game will end in a draw
Playing a white black deck with Ajania OPutlander Chaperone. I used the ability to look at the top X amount of cards where x is my life total and put any with mana value 3 or less on the battlefield (26 cards looked at, 13 placed).
Some of these cards triggered life gain when entering, others created token on life gain or 1/1 cat tokens. The arena was looping around a few times then the warning started. I had no option but to keep resolving and then it drew the game.

The Back Arrow isn't working.
The Back Arrow in the deck details screen isn't working. Once I'm in the details screen I can't get out unless I go back to the home screen and abort the deck building.

Achievements not triggering
I've noticed a trend with achievements not triggering - if it's an achievement that is tracked over multiple games, it seems to be tracked correctly.
However, if it's an achievement that is tracked over one game, it won't trigger correctly.I've noticed this specifically in the "reach over 50 life in a single match" and "attack with 15 or more creatures in a single combat step" achievements.
I've achieved both of these multiple times, in the starter deck duel event.
I know this is a valid event to get these achievements in, as I've earnt multiple other achievements while playing this event.As I said, it seems to work fine with the achievements that are tracked over multiple games, so the issue must be related to the individual game tracking.

Unable to target Bloodletter of Aclozotz
Unable to target Bloodletter of Aclozotz. It is not being recognized as a creature for no apparent in game reason. See screenshots of me attempting to target with multiple removal spells. Edit: this forum is not allowing me to post the screenshots for some reason.

TSUGE CHEATER
Why is this user "TSUGE" still playing the game. They start games and they're never present to actually play them. This is the experience you offer to your paying customers. Complete absolute garbage dude. It's a struggle to try and play this game. Fix your game man. Get rid of the people exploiting it get rid of the people cheating. Get rid of the computer controlled players that play the exact same cards every time. It's a joke. How many times do I have to wait 100 to 200 seconds and be forced into a draw because there's not actually an opponent there to play the game. How many times do I play a game and the opponent plays two turns and then disappears and is gone for the rest of the game and then I play another game and the guy starts a game and he's not there from the start of the game for the entire game and the excruciatingly long painful wait time for the person's turn to end is not worth waiting through so I just concede all these games when I should be winning them all. But your game is forcing me to just waste my time. And I'm a ******* paying customer. What gives man what a joke

Slumbering Walker Incorrect Display For Trigger
Slumbering Walker's triggered ability at your end step displays a ORANGE DECLINE button on the right, and expects you to CLICK ON Slumbering Walker to confirm the ability.
This goes against every triggered ability with an option to confirm/decline in the entire game. Other abilities will have decline button in BLUE, not ORANGE.
If I've been taught by the game to press ORANGE to select things that are beneficial to me, why is this ability orange to benefit my opponent?
I understand small case scenarios where I might WANT to decline, but not even HAVING confirm as an option on the right and wanting me to click ON THE CREATURE is downright absurd.
This mistake cost me the game in the attached clip, and this was in the Arena Direct - Sealed Lorwyn Eclipsed Collector Booster Box Event.
PLEASE change this to AT LEAST have the decline button be BLUE.

Priority on redirect/retargetting
- Play a removal spell (eg Bitter Triump) targetting an opposing creature
- Opponent plays a redirection spell (eg Redirect Lightning)
- You click "Resolve" to let the redirection spell resolve, still planning to take a decision after you get to know the new targets
Expectation: you get a priority window before your removal spell resolves.
Actual result: Arena will pass all priority and resolve the whole stack4 votes -
Ghostly Prison Not working?
So I have 2 Ghostly Prisons on the Field and somehow the person I'm playing against who is all tapped out of mana is able to attack my planewalker with their creatures?!?!?!
I checked the board and there is nothing they can tap for mana and no abilities that could allow them to attack .
The player's name was EdamameCheese.
I think they were cheating somehow. I have it caught on stream.

Freezing on PC and android
I've been experiencing games freezing on both android and PC. The display will freeze and I will be unable to interact with it. I can force quite and when I rejoin there are various graphics bugs occurring (multiple displays of overlapped text, black boxes covering the screen during games, etc.) until I force quit once again.

lion's eye diamond
MTG Arena didn't recognize LED as a mana source and didn't let me respond to my opponent's Chain Lightning by cracking LED to activate my food.

Lion's Eye Diamond - Requesting event reimbursement.
LED Does not hold priority as an activated ability. May be due to coding as a mana ability?
Had a guaranteed win (likely) with LED + Underworld Breach + Brain Freeze. Critically important to have the combos function properly if powered cube is going to be a format on Arena.
Requesting event reimbursement.
