Definitely! This is more about streamlining deck building for those who want it than removing features that people enjoy. If you want to manually make every land a different printing, you will still be able to do that in the designs we have been looking at.

Cool feature requests, here's my feedback:

1. Sometimes it's hard to keep context between matches because the match scene is different from the out-of-match scene. Seems like a good QOL addition, if it's easy.
2. This one is probably a little harder, but I can see the utility of not breaking the friend challenge between matches. I think it would be something we could only do through the friend menu, (not direct challenge) but it's an interesting suggestion.
3. I'd love more random options. Like random pets for example, or random avatars. I always used to play Street Fighter using the random fighter button, so random decks sounds fun like that. I agree there would have to be some limit to the selection to make it work, maybe favorite, I'd have to put some thought into how that works from the UX standpoint. I like the idea, though.
4. This would have to only be for friend challenges because competitively no one wants to give up the knowledge of a card ...

Not sure when we get there, but this is definitely something on our radar. As the game gets more and more lands (and card reprints!) with each set, the collection interface gets filled with lots of duplicate information. I'd like to be able to collapse duplicate cards into a singular item with selectable printings, but that's a fair amount of work for the UI.

Keeping an eye on this thread for other feedback. Thanks for bringing this up!

We weren't aware this change was coming, so a big shoutout to those of you who brought it up with some time to spare! Twitter's cool and all, but Jay and I are much more likely to catch things here, which is what happened this time. I'm glad we were able to solve this without disruption to anyone's game.

Working on fixing it, but the solution ended up being more involved than initially expected (and why we didn't have time to get it fixed for May). It's one of my priorities for the M21 release. Sorry for the wait!

Update: We're officially back on the menu.

It's more that we hadn't been aware of the issue. We're working on a fix this week, not sure when it'd go live though (very likely M21-release at the latest though). #wotc_staff
