The card shown has completely different text than what I see for the English version.

JP: When this card enters, choose a card you control and a enemy card to fight if the enemy card loses its exiled.

ENG: Whenever you attack, you may sacrifice another creature or an artifact. If you do, create a 4/1 black Skeleton creature token with menace that’s tapped and attacking.

Taking the moment, I want to inform you that all event explanations appear in lines of code.
The Carnival/Carnage card is a more specific error, when the card is in the hand or in the graveyard it is normal, but when it is in exile, both the name of the card and its explanations are changed to ##### ### ##

Text is not displayed when playing the arena in Japanese.
Since there are cards dedicated to the arena and there are cards whose text is different from the actually printed card, the text of the actual card cannot be used as a reference.

Playing on Windows 10.
The card "Mace of Destruction" is missing the translation of the devil-proof effect.
Hoping to be helpful :)

I have created an app that allowed to translate the client prior to version 2021.9.0.3880.888241. Unfortunately that version has more rigorous checksum checks and Arena is rendered unusable in the process. Modified files are deleted but original ones are not being downloaded.

My project mtgpopolsku.pl was used by many players that don't know any of available languages. My voluntary (and completely free) work was beneficial to you and I even have permission to do so.

Please add a way to translate the interface and card database and to add new language to drop-down menu in settings.

The German translation of imoen Blue-White Backside is different from the english one.

In German it says one creature while it says each in english

Bom dia!,existe uma carta que está dizendo uma coisa no texto e faz outra,a carta é um encantamento preto de 2 manas chamado procissão de carniçais,no texto diz que eu coloco uma ficha de zumbi decomposto se uma criatura não ficha morreu nesse turno e só desencadeia uma vez a cada turno.
Porém eu joguei com o bot pra testar a carta e descobri que quando qualquer criatura ficha ou não ,incluindo a própria ficha de zumbi decomposto o encantmento é ativado e cria uma nova ficha fazendo um looping infinito de criaturas,uma vez por turno.

Metallic Mimic can be "Any" creature type. I can't pick "Shrine" as a creature type?

秩父の学部長オーガスタをコントロールした状態で攻撃した際、秩序の学部長オーガスタの能力が誘発しますが、その際『あなたがコントロールしていてタップ状態である望む数のクリーチャーをタップしてください』と、正しくない説明文が表示され、正常なテキストでのゲーム環境となりませんでしたため、750ジェム、または5000ゴールドの補償を請求します。

When upgrading Rogue Class to Level 3, the text of the card states "CARDNAME" instead of Rogue Class. This error does not seem to appear at any other time when examining the card.

In MTG Arena, I found a wrong text in Japanese version of Teferi, Who Slows the Sunset. The text says untap and tap opponent's permanent.
