This exact problem is happening for me as well. I've been trying to create a Traxos historic brawl deck, and no matter what, the same thing happens

As of 12/28 at 12:20 pm EST...still not working

When will wastes finally be fixed?! This is a scandal!

Still an issue on December 26th (Mac)

Every time I try to create an artifact colorless Historic Brawl deck I keep getting an error saying Network Error Deck Creation Failed. Please try again Later. I've been getting this error EVERY DAY since the Waste lands came out. I can't even save the deck or anything due to this error. This is being submitted on 12/26/2022 hoping to be fixed soon.

23rd of december, still getting the network error on Historic Brawl... Probably won't be fixed before next year...

This is still happening as of now. I’m genuinely annoyed. This seems to only happen to colorless commanders. Wtf is the point?

Wizards this happens everytime with multiple wastes.

still happening today. extremely annoying, pretty ****** i wasted currency on the full arts and they don't even work

Patch 2022.22.10.4411.977745 -> the save/network bug is still there in brawl

To Confirm this is still broken, work around in historic brawl I found is to turn off the "suggested lands" and then add another land (plains worked for me) then remove the wastes and add the 40 plains (or whatever you need)

Yes, O have had the same issue when trying to save an Ugin Historic Brawl deck, as well as an Historic colorless deck. Also, Waste cannot be added manually, they auto ad as I add colourless cards to my deck via the deck builder, but the save then doesn't work.

I am having the same issue the game won't save any decks that have wastelands in them

Steps to reproduce bug.
Start new deck build. Format historic brawl. Chose a legendary colorless commander( or say liberator urza's battlethopper). Put in 59 colorless spells. Then add 40 BASIC WASTE LANDS. Save. Network error.
Platforms.
Pc, an android.
Actual results
When you try to do the steps stated it will not let you save the deck. BASIC WASTE LANDS ARE BUGGED. Take the basic waste lands out it works just fine. Is this from what I can tell any print of waste as I have the full border art an it won't work either.
Work around.
I wish if someone knows a way let me know pls. This is as another report stated, game breaking! I mean there are 40 or more colorless lands you could use but unfortunately I'm about 10 away form having enough for that to be a viable option and most of them are rare's. WASTE is a much need card PLEASE FIX asap. A hey we know, we're working on it goes along ways. Thanks

Same here. It's the pits

I just want to play Kozelek, fix your game wotc.

I have been able to add Wastes to a Historic deck, but I still can't add them to my Historic Brawl deck for some reason.

please fix this wotc it's been a week now.

i am also experiencing this same bug. It will not let me save my colorless deck after I add Wastes to it.

I am also experiencing this bug in Historic Brawl, but curiously it mainly appears to be a problem specifically with colourless commanders (currently trying to build Karn, Living Legacy) - very annoying as these are the ones who want them the most. I have made monocoloured Historic Brawl decks (Azusa and Chandra, Torch of Defiance) with an eldrazi package that appear to have no problem at all in adding 1-2 wastes.
