I had on the board an "Alseid of Life's Bounty" and an "Ajani's Pridemate".
The opponent attacked me and I blocked with "Ajani's Pridemate". Before damage, I used Alseid's ability to give my Pridemate protection from the color of the attacking creature.
Even with protection, my creature suffered damage and died, while Protection is supposed to prevent any damage caused from sources of that color.
No screenshot was taken because I didn't have enough time to do it.

1) [[Entrancing Lyre]]'s Ability for X=1 was put onto the stack targeting opponent's [[Riptide Turtle]] (No buffs were on turtle, it was still a 0/5).
2) Opponent Cast [[Heliod's Intervention]] for X=3 targeting the Lyre and 2 of my enchantment creatures.
3) Intervention resolved; targets were destroyed.
4) Lyre's ability resolved; Turtle was tapped.
5) Turtle remained tapped for remainder of game. This remained true even when Lyre was exiled to pay for the Escape cost of [[Voracious Typhon]].

no reward for standard event

Nearly the same problem then above.

I had one card in my hand and a creature on board. Opponent plays Ashiok and uses his -3Ability. He exiled my card in my hand but i don´t get my creature from board into my hand? after this Ability i had 0 cards

playing theros sealed. game froze. claimed connectivity issues. I have gig internet. Cerberus pet still works. opponent just stopped playing. don't want to concede because it will count as a loss.

The new Color Challenge event is showing as already fully completed, despite not having existed before the current patch. Replaying does not award the rewards. In addition, there is no restriction on the deck you choose to use for the final "challenge" against another player, but once you choose a deck it locks it in permanently.

Arena has been buggy again lately. All my other Internet based apps work fine, and there is no firewall blocking.

I mutated a gemrazer on top of a Nissa Who Shakes the World elemental land. The gemrazer was shown as a 4/4 creature (it's natural state, unlike others who have had an issue), but was not a 7/7 as it should be with the three +1/+1counters on it. This cost me the game as i could not pressure trample damage through. As far as I can tell, he also could not produce Mana, though I am not sure if he should still be able to on paper.

It let me pay the entry fee (500g) for a standard event. However, when I click the select deck in the bottom right and select a deck, it doesn't let me lock it in. Tried with several different decks legal in standard.

I also tried the other button (+) for selecting deck, and got the same issue.

Rank not increasing despite wins

My ikoria lvl 20 mastery pet is also missing. please attach to current thread

Luego de la ultima actualización de la semana del 12 de marzo, al abrir el juego mi pantalla se queda en negro con el mouse del magic arena pero no pasa nada mas, des instale el juego y lo volví a instalar y pasa lo mismo

Dispute. It always costs 1 blue mana. It also glows as she can be played on a clear stack.

Every game I start has black unreadable cards. Restarted, re-installed, updated graphics drivers, nothing helps. Game is massively broken!

Cerulean Drake lost protection from red when taking doublestrike damage from Robber of the rich with Embercleave attached to it.
Lost game because of this bug.
When is this being fixed? I've read a few posts in the forums and this bug has not been fixed since last year! Weak effort on Wizards part for not addressing this sooner.

Seems like a really bad bug due to mono reds massive impact on standard right now!

Every time I unlock a planeswalker card through the mastery pass progression the game shows me two copies of the same card in the rewards screen. I do not actually receive two cards, however. For clarity, these are the planeswalker cards that are visible every ten levels in the core set mastery, not ICRs. I have not had this happen with any other cards.

Renewal reward seed not giving rewards. Just a blank screen with a green continue button that leads to the mastery track.

Sideboard is not available after the first match (2nd and third game without option of sideboarding antyhing).

Error data prt sc attached.

Unity keep crashing more and more frecuently.
