What HTML5 Canvas tools should I use to build a card game?

I'm looking to create a card game using HTML5 Canvas and JavaScript, and I want to know what Canvas tools could make my life easier.

I've found CreateJS and taken some notes on it:

• Suite of libraries/tools for simplifying complex interactions with HTML5/CSS/JS
  • EaselJS - Abstraction layer on top of HTML5 Canvas
  • SoundJS - Abstraction layer for HTML5 Audio
  • TweenJS - Library for animating HTML5 and CSS properties (cool easing demo)
  • PreloadJS - Library for preloading assets (JS, images, sounds, data, etc.)
• Documentation seems thorough
• Lots of demos; no Getting Started Guide/Tutorial to be found
• Free and open-source (sponsored by Adobe and Microsoft)

What other tools/engines would be useful for making card games for the browser?

Bonus points for tools/frameworks that would help me outside of HTML5 Canvas. I'm using Node.js on the backend, and planning on using Socket.IO/Express/MongoDB, since that's what I know.

Note: I've collected some notes on game engines/tools (including the CreateJS notes above) in this Google Doc. Feel free to add your points to this doc.
