DB Custom Card Frames+ is a custom card tool for DB that enhances the customization options for Duelingbook, an online Yu-Gi-Oh! dueling platform. This add-on extension, developed by anteikumio, is designed to work in conjunction with Eyal282's Duelingbook Extension "Dueling Book Unlock" (version 9.3 or later).

With DB Custom Card Frames+, users can import their own card images as png files at full size. The process is simple: upload a full card png as the image of a monster, spell, or trap on Duelingbook, and then add the text "This is a custom card." at the end of the card's effect. If done correctly, the image will expand to cover the entire card, including the border, frame, and effect box.

In addition to the image import feature, DB Custom Card Frames+ offers a legacy method that allows players to customize their custom cards with various frames, colors, and attributes. The frames include options such as "Positive Circuit Monster," "Dark Synchro Monster," "Evolve Monster," "Switch Monster," and "Token." Users can also add the "DREAM-Attribute" to their cards.

Other notable features of the extension include unique frames for Gemini Monsters, colors unique to the Egyptian God cards, and the ability to assign custom types to monsters by adding the sentence "This card is Something-type" to the card's text.

DB Custom Card Frames+ is a free extension available on the Chrome Web Store. It is a valuable tool for Yu-Gi-Oh! players who want to add a personal touch to their custom cards on Duelingbook.
