The Judge Classes are back! It's been a long way, but we have an updated version again for this study material for judgelings, up to the Hour of Devastation changes, that you can find here:

We're trying to keep the documents updated, so in no time we'll have a new version, with the Ixalan release, and we'll be announcing changes as soon as we have it.

Regards!
