Commander Guard от Thekmodo

Warns you before exporting high-powered Commander decks into casual pods. I embarrassed myself a few too many times grabbing a random deck and having it be Bracket 4. Asked Claude to help throw together a little tool to help me, and you if you want. It was mainly uploaded to allow it persistently across sessions.

Checks primarily on a list of mtg deck sites to find the word bracket and a number to see if something is flagged 4+. Since not all deck sites show the bracket all the time it has a backup list of gamechangers and warns you if you have more than 3.
