Upcoming MTG Arena Events

Additional events added to MTG Arena. Read the MTG Arena Weekly Announcements to learn more!


  • Golden Packs arrive – Earn progress on the meter when purchasing BRO Packs in the store
  • Added a new store icon, which will also show you the progress of your Golden Pack reward meter
  • None of you can tell, but Autumn finished the Bucket Node Tool for the editor, and I think it made a big difference to quality of life for art.
  • Improved the game’s ability to detect corrupted AssetBundles. This should reduce the scenarios requiring a player to manually delete files from their disk.



  • When paying for generic costs Auto Tap is now more likely to tap a “painland” (for example Adarkar Wastes) for colorless before tapping other lands
    • Similarly, Using the “qq” shortcut to tap all mana sources now defaults to colorless mana when tapping painlands.
  • We’ve adjusted the weights so that permanents that produce variable mana (like Powerstone Shards) tap later than similar permanents that don’t. In practice, this means that if you try to played Collected company on turn 3, it will tap your Llanowar Elves before your Elvish Archdruid. If you don’t play elves, trust me, this rules.
  • When doing a “name a card” search, the system is much more robust now. For example, “Meathook” will now find “The Meathook Massacre” when previously it wouldn’t.
  • We’ve adjusted the location of the mana pool, counters on the player, and “you must discard to 7” warning. Instead of being up in the middle of the battlefield, often in the way, they run alongside other icons on either side of the avatar, below the cards.
  • Cards that use 2brid mana now always prompt for what cost you want to pay.
  • Autotap has gained a better understanding of cards with discounts that it can’t actually afford, and it now knows not to give you a stop to stare at it and go “I can’t actually cast this.”

Bug Fixes


  • Fixed a bug that could prevent importing a deck that used Esika's Chariot
  • Fixed a soft lock that could occur when a friend cancels their Friend Challenge while you’re attempting to join the match (How rude!)
  • Fixed an erroneous “Cancel challenge?” pop-up that could occur when joining a Direct Challenge after playing a Friend Challenge
  • Fixed a visual issue with accepting a Friend Challenge that could lead to overlapping UI
  • We have done further work to keep audio from dropping out
  • Fixed a bug where scrolling in the Decks screen could become unresponsive
  • Fixed a bug in the deck builder where the icon and tooltip on invalid decks would sometimes disagree on the counts of problematic cards
  • Fixed a bug where “Suggest Lands” wouldn’t add any lands for a purely colorless deck. Now it does, since someone’s certainly going to try this with BRO.
  • Fixed a bug where the Orb rewards weren’t displaying properly when hovered over on the Mastery Track
  • Made several fixes that should improve UI layering and reduce visual bugs across the menus (Magic makes layers tricky in many ways)
  • Fixed a bug where a sleeve could get “stuck” in the UI after mousing over it in the profile screen
  • Fixed a visual bug on 4:3 devices where some disclaimer text in the store could get cut off
  • Fixed an issue where artist credits on split cards weren’t displaying correctly. They were super tiny.
  • The hint bar colors for MDFCs was flip flopped. It has been flop flipped.


  • Copying a Graven Archfiend with the additional cost paid was resulting in each of them triggering twice, for a total of four triggers. Fixed!
  • Planeswalkers with Compleated were showing up as castable even when you were missing a color. Autotap is now chilled out about this.
  • Fixed an issue where a creature targeted with a kicked In Thrall to the Pit was still being sacrificed even if it was phased out. I think this is a flavor fail, because just being removed from the flow of time doesn’t make you not die of demons in your brain when you get back, but it’s rules correct.
  • Planeswalkers that can turn into non-planeswalker creatures while being attacked were still showing up as attackable when assigning damage. Now they aren’t! If Grand Master of Flowers turns into a dragon he’s now safe from attackers!
  • If you cast Extinguish the Light targeting an indestructible creature with mana value 3 or less, you weren’t getting the 3 life. Now you do! Congrats of finding the world’s worst Revitalize!
  • Fixing an issue where using Goblin Morale Sergeant’s Enlist ability with no cards in your deck caused a crash.
  • Did you know that if you used Band Together you could ALSO target one of the creatures you control that you targeted to deal damage to receive the damage? No, no one knew. No one ever tried it, because why would you? But it’s fixed.
  • If you control a Werewolf Pack Leader and a Maskwood Nexus, then you turn the Werewolf Pack Leader into a NOT human, Maskwood was overriding the Non-humanness, but it doesn’t now.
  • The Read Ahead text at the top of Read Ahead sagas now displays as a keyword should, instead of being in italics. I have only myself to blame, and I hope we are able to learn to trust again in the future.
  • Suncleanser wasn’t pulsing when preventing counters, but now it pulses again!
  • Cards with showcase styles that were part of a mutate stack, then got bounced back to hand or destroyed were losing their styles. It’s fixed!
  • For a while there were perpetual counters, but now there aren’t. As a result, the hanger that explains perpetual no longer refers to them.
  • Reduced text parallax in rules textboxes when cards are at the edges of the screen (The rules text used to appear slightly different when a card was viewed on the far right or left side of the screen)
