chrome extension: Yu-Gi-Oh Card Radar

# Yu-Gi-Oh Card Radar

A lightweight Chrome extension that monitors newly released Yu-Gi-Oh cards and notifies you automatically.

Instead of manually checking card databases, **Yu-Gi-Oh Card Radar** watches the latest releases and alerts you when new cards appear.

## How it works

The extension uses the public API from YGOPRODeck to monitor newly released card sets.

3. A Chrome notification is shown

4. The card appears in the popup list

## Popup View

The popup displays recently detected cards including:

• Card name

• Card type

• Release date

• Direct link to the card page
