There’s a site – tappedout.net, which lets you draft cubes with AI bots and/or people. You have to register to the site to do cube drafts, but as far as I know, the registration was pretty painless.
That way, if you’re wondering how my various cubes play out, you can do some sample drafts to find out. The AI used to be pretty dumb, but it’s gotten better. Still, nothing beats people, so if you can get some people together to do a group cube draft, that’s perfect!
