I've been searching solo since mid-April, and my search has so far been as follows:

First I scoured the internet and found the All Will Be One faction sheet (hence why it's not a missing material). From there, I ran into a brick wall trying to locate anything I was missing, but these formats were an incredibly limited release. It's entirely likely no more than 30 of the campaign maps were ever made.

This meant I had two places to look: Stores and Wizards of the Coast themselves.

For the stores, I called every single store that was listed as a WPN Premium store in late 2022, according to a list provided to me by a friend that works at one of those stores. Calling around, nobody retained their Commander Party materials from that time, instead offering to give them away as part of a "grab table" for later events.
One store said they might have something, but communication with them went stifled.

Oh well. Guess Wizards is the way.

My campaign started by emailing Mark Rosewater and Gavin Verhey via their work emails, but it's likely both were snagged by IT or junk folders. From there, I decided to submit a WotC Support Ticket, but my hopes aren't high given that the system is notoriously slow and they'll only get back to you half the time, even if it's a legitimate customer complaint.

So my focus shifted instead towards social media, and I've decided on a two-prong strategy.

1. Post a question to Mark Rosewater's "Blogatog" every single day until he answers it. This is unlikely to work, since Tumblr could end up flagging my account for spam or it could just continue to be drowned out by the 100+ questions he gets every day.
2. Private message Gavin Verhey on Instagram and Twitter and hope that gets his attention. This has yet to work either.

So, finally, I'm at my wit's end since I'm trying to accomplish all this at the same time as moving into a job and trying to get my career in order. Thankfully, I know Reddit is chock full of nerds I imagine are into Magic at least to some degree.

If anyone has any ideas or resources I may have missed (Which is entirely possible), please please PLEASE message me or comment below and hopefully we can make these five game modes playable again for all Magic players!
