Bastion

A free and open-source Discord bot for looking up cards and other useful information about the Yu-Gi-Oh! Trading Card Game, Official Card Game, Rush Duel, and Master Duel video game.

Get started with searching for cards using <> in your messages! For Slash Command documentation, look in docs/commands. For everything else, please refer to the old Bastion Classic repository.

Thanks to YGOPRODECK for sponsoring Bastion. Prices provided by Bastion are YGOPRODECK affiliate links.

Card images and most card data are sourced from Yugipedia via YAML Yugi.

If you do not want Bastion to be used in a channel, deny it the View Channel permission. Otherwise, all of the above permissions must be granted to Bastion in each channel it is available in for it to work correctly.

If you do not want Slash Commands to be used in a channel, this can be managed per command in the Integrations tab of your server settings. Alternatively, you can blanket deny the Use Application Commands permission for the individuals or roles in question, but this will apply to all bots.
