alt Hacker NewsThis is a pretty common format called cube.
You can grab a list from somewhere like cube cobra. Buy the cards, or use an online draft tool or print a bunch of proxies and play. Its a fun way to play with cards that are just sitting in bulk boxes and play without having to buy a whole booster box
Hmmm sounds cool, I had heard about this before and since forgotten. I think part of what I would like is to give some of the old and weird cards in my collection some play though, rather than just playing a well known cube- but then if they're too weird they might not work at all together.
