Magic The Gathering: Arena Dev Tracker

Showcase Vorinclex is scheduled to also be available with the Strixhaven release.

The borderless Foretell cards are not scheduled to be on Arena. I think some early published content may have gotten wires crossed between these cards and borderless planeswalkers and Pathways.

Narfi, Egon, and Harald will be available for purchase in the deckbuilder (along with other KHM showcase styles) when Strixhaven releases.

(These three were locked off for an event that ultimately had to be pulled at the last minute. :( Sorry for the frustration.)

The client does know the banned cards, and right now it knows how to apply a red filter over them in the deckbuilder so that you can see they are banned. It can absolutely be taught to do other things with that information, but as with everything, that comes with costs, and balancing those tradeoffs is a constant part of game development.

I'm not sure what you mean here by event descriptions. All events have some amount of descriptive text which usually explains the basics of what's going on. What additional description would you like to see?

Ban lists are a different question. They were migrated online so that they could be updated more rapidly if needed - like in case there was an official B&R, or a card turned out to be very oppressive in ways we knew players wouldn't want more of. If that happened while the cards were listed in the client, that meant we were picking through several languages' worth of localized text to make updates on a short timeline. That change also opened up the option of doing events with long ban lists, like the progressive Historic Shakeup that just ended, which would never have fit on the event page before.

Honestly, I don't expect that we will go back to writing out the ban lists in text. It would be a pretty hard sell to move back to the riskie...

Historic Challenge is honestly a weird duck. It's one of the only event types with 8 win rewards, which makes its reward track longer than everyone else's - and awkwardly, that UI element starts to break down if you try to cram it too full of stuff. The external link lets us list all the rewards without breaking the interface, and also list all the different mixed packs in the rewards, and also mention the reward that everyone gets on entry (yet another thing that's weirdly unique to Historic Challenge, compared to other events at its level)... Basically, up until now, that link has been doing just enough to skate by despite the event not looking great.

Well, no longer! We're reconfiguring the structure so it can fit cleanly in the client, and you'll see the new version during Strixhaven.

For constructed, Standard-based events use the battlefields associated with sets still in Standard, while Historic-based events use the battlefields associated with sets that aren't legal in Standard.

One day? I was assured that this will be the permanent look of Historic going forward for ever and ever...

(But yeah, we are all very happy that everyone's been enjoying themselves!)
