When I logged in at 11:01AM EST arena told me what sets are rotating. Then when I clicked on the renewal egg, 4 of the cards were from sets that had just rotated out.

For example when we search "時を解す者、テフェリー"(Teferi, Time Raveler) at deck building in Japanese version, we couldn't find it with the card name.
We have to input additional characters(ruby) to find the card with the current searching system.
[時を解す者、テフェリー] is like that [時(とき)を解(ほぐ)す者(もの)"、"テフェリー].
It's too difficult to search.

We want to find out cards with card names themselves with Kanji and/or its card name pronunciation without Kanji.

Not only do you need to ban this card, but fire someone from the R&D department for coming up with and developing that card. What the heck went on in there that this made it to print???

Turn 2 wins in Standard???????????

The new college sleeves with Strixhaven actually became BUGGED when the set released today, 4/15. Attached is a screenshot.

Finished the quest to get Selesnya Conclave deck today and none of the cards were added in my collection.

The deck is completely empty, appart from the basic lands.

I had none of the cards before and none of the cards were added after getting the deck: every number to the left of the cards are red.

Selecting and searching for an advanced filter card type in Japanese does not show anything
Switching languages will improve the situation.

Changelings are incorrectly not counted as cat/elementals etc. when determining eligibility for Kaheera.

I had redeemed the Strixhaven sleeve codes before the set came out and they worked fine, but since the update they appear on the card sleeve page as just additional copies of the standard card back and appear as standard backs when deck is played.

Ask I was opening packs 10 at a time of ZNR I would get an error advising unable to open booster and then it try to reconnect to server. When it finally is able to reconnect to the server I have lost 10 PACKS... This has happened to me 5 times now. Please replace 50 lost packs asap.

My Etra Life sleeve is no longer available

Strixhaven card sleeves I had prior to the strixhaven update are now regular card sleeves. I cannot redeem them again. please fix as they are necessary for the college cup.

It was advised in an article that the Mystical Archive cards would take up a common slot in the 8 card arena packs. That is simply not happening, I have opened 150 packs so far and the MA card takes up the uncommon slot 60% of the time and the rare slot 40% of the time, not a single time has it replaced a common. I would like a refund of half my gems spent for these packs 18,000 (half of 36k) please, since this is obviously a bug according to this article. https://magic.wizards.com/en/articles/archive/magic-digital/mtg-arena-state-game-strixhaven-school-mages-2021-04-07

Selecting the + button to build a new deck does nothing. Changing any deck type (standard, historic, etc) has no effect on this. I can modify existing decks (Edit Deck) but I cannot create anything new.

Sideboard

After the Kaldheim update, I started a sealed deck event. On the deckbuilding screen, all of the cards are missing the set symbol. Most cards are fine otherwise, but a few of them are missing all text. The title bar and main text box are completely black. A few cards have just half of the text box covered in black. It appears to be mostly restricted to snow cards, but it's not all snow cards

Completed the daily quest and received the Selesnya Conclave deck from Guilds of Ravnica instead of the deck for the current standard.
