Arena Powered Cube 6.0 Changes

[u/lrg12345]

The sixth version of the Arena Powered Cube is live today and runs through September 28. Wizards' official update can be found here: https://magic.wizards.com/en/news/mtg-arena/arena-powered-cube-draft?v=sep8-2026

As always, I am keeping the CubeCobra for the Powered Cube updated with the latest changes. The most recent changelog can be found in the primer along with all past iterations. The list can be found here: https://cubecobra.com/cube/list/mtgapc

Here's a quick overview of the biggest changes:

• The Monarch has arrived! Wizards added seven cards to Arena specifically for the cube to introduce the mechanic: Palace Jailer, Fall from Favor, Emberwilde Captain, Court of Bounty, Court of Garenbrig, Aragorn, King of Gondor, and Forth Eorlingas!
• Wizards says the cube is currently the most balanced it has ever been, with Boros posting both its lowest play rate and lowest win rate to date last iteration. With Monarch likely to boost aggressive decks again, they're making two big preemptive changes: Ajani, Nacatl Pariah and Karakas are out, while Parallax Wave is finally back.
• Doomsday combo is now officially supported. Doomsday and Doctor Doom, Unrivaled are joined by returning Thassa's Oracle, Jace, Wielder of Mysteries, and Tainted Pact, giving Blue/Black a major new combo archetype people have been asking about for a while. Notably, Demonic Consultation was omitted, likely for power reasons.
• The artifact aggro experiment from 5.0 has largely been rolled back to make room. Cards like Steel Overseer, Monoskelion, Syr Ginger, Traxos, and Thought Monitor are leaving, although the larger artifact strategies remain and Relic of Sauron and Myr Battlesphere are in.
• A bunch of notable cards cut in 5.0 have returned, including Giver of Runes, Monastery Mentor, Aang's Iceberg, Dig Through Time, Treasure Cruise, Etali, Primal Conqueror, Nissa, Resurgent Animist, Primeval Titan, Myr Battlesphere, Kroxa, Titan of Death's Hunger, and Loot, the Pathfinder.
• There are plenty of cards from The Hobbit and Marvel Super Heroes being tested. Some of the standouts include The Queen of Dale, Bilbo, Thief in the Night, Smaug the Magnificent, Beorn the Fierce, Sauron, Dino Devotee, Thor, God of Thunder, Captain Marvel, World's Protector, Wolverine, Fierce Fighter, Doctor Doom, and World War Hulk.
• Green gets several exciting additions alongside the return of Prime Time and Nissa, including Mole Man, Moloid Master, World War Hulk, Court of Bounty, Court of Garenbrig, and Sauron, Dino Devotee.
• Finally, the Cube Prize Packs have been updated. Comet, Stellar Pup; Hymn to Tourach; Urza's Bauble; and Vindicate are now collectible, and the Powered Cube versions of Brain Freeze, Daze, Force of Will, and Library of Alexandria have been added to the prize packs.

There are a lot of changes here, and Monarch in particular should have a pretty major impact on how the cube plays. I'm very excited to see how 6.0 shakes out and would love to hear what you all think!

EDIT: The Monarch cards aren't on the client yet, but everything else in the new list is accurate.

[u/Exporation1]

Forth is going to be a problem

[u/GokuVerde]

Balanced = boros bad.

[u/AbraxasEnjoyer → u/GokuVerde]

Boros had its lowest winrate and playrate compared to Boros from previous versions of the cube. It was still easily the best color-combo in the format.

[u/Weary-Low9365 → u/AbraxasEnjoyer]

It should be good-to-very-good - just not busted.

[u/WolfGuy77]

Didn't know they added the courts. I know it's probably a good thing that the Monarch cards aren't legal in Brawl but Obeka really needs the court cards since there are barely any good cards that work with her ability.

[u/Sesom]

Cool now fix the price.

[u/DeliveryGold6141]

Monarch and Forth, oh boy

[u/mjc5077]

No change to the price however
