The only real changes made to the cube are replacing double faced cards, cards whose printed templating is very different from modern templating and adventures.

original description for posterity's sake:

This is my pauper cube, originally hosted at CubeTutor (cube #78807). It's been almost five years in the making, and overall I think it's the cube I'm most proud of. It's also the only cube that I actually have built in paper.

The environment is generally pretty high powered as pauper cubes go. My philosophy with this cube has been to enable as many types of strategies as possible, so whether you want to slap Armadillo Cloak on a Lagonna-Band Trailblazer, wipe the board every turn with Pestilence while your Guardian of the Guildpact chips away, or go infinite with Peregrine Drake and Ghostly Flicker, there should be something for you. I also make it a goal to ensure that every color can be played in both fast and slow decks, so a few early power picks don't have to dictate your entire playstyle.

At a fundamental level, pauper is about playing good, wholesome magic, with a focus on creature combat and incredibly efficient interaction. That's more or less what this cube offers.
