"Deck Test Tool for Pokemon Card Game Players" is a Chrome extension that enhances the official Pokemon Trading Card Game website's deck-building tool. Players can now test their decks before physical play, providing a preview of card draws and overall deck performance.

The tool offers two key features: Firstly, players can easily view their starting hand, side deck, and next draw from the deck at a glance, aiding in pre-match preparation. Secondly, users can test their deck solo, allowing for a rough assessment of deck dynamics before physical play.

Please note that this extension is not an official feature of the Pokemon Trading Card Game, and users are advised to utilize it at their own discretion. Recent updates include improvements in usability, such as preventing unintentional actions and enhancing overall user experience.
