[RPG] the Plane Shift series considered


Wizards of the Coast has released multiple Magic: the Gathering supplements for Dungeons & Dragons (not including the Guildmasters' Guide to Ravnica) as part of the Plane Shift PDF series.

What would these be considered? Would they be considered homebrew? Or would they be more akin to the likes of The Tortle Package or Locathah Rising?

On a further note, are the Plane Shift PDFs Adventurers League-compatible?

Best Answer

They're untested, unsupported material that happens to be published by WOTC.

Starting with Kaladesh, the item descriptions on DMsGuild have contained this:

The game mechanics in this supplement are usable in your D&D campaign but are not fully tempered by playtests and design iterations. For these reasons, material in this supplement is not legal in D&D Organized Play events.

It's similar to the disclaimer found on Unearthed Arcana articles:

The material in Unearthed Arcana is presented for playtesting and to spark your imagination. These game mechanics are in draft form, usable in your D&D campaign but not refined by final game design. They are not officially part of the game. For these reasons, material in this column is not legal in D&D Adventurers League events.
