Guzztool is a Chrome/Firefox extension with many subtools that let you change Pokemon Showdown in different ways:

• Zorua's Spoilerguard prevents spoiling the suspense of Pokemon Showdown battles by hiding the end-of-battle controls until the final turn ends.
• Pikachu's Elo Hider hides your elo changes at the end of battles to reduce stress.
• Exploud's Announcer adds the Pokemon Stadium 2 announcer to battles.
• Meowth's TTS uses text-to-speech to read out battles and replays.
• Togepi's Lucky Button adds an "I'm feeling lucky" button to the teambuilder that generates random sets from usage data.

Steps to build this extension from scratch:

• Clone this repo
• git submodule init
• git submodule update
• npm install
• npm run build for development or npm run export for minified production version + zip
• Results will be in dist-dev/ or dist/ respectively

Adding new subtools is relatively straightforward. If you build one please contribute it to the repo.
