Here is an Excel Spreadsheet listing the contents of my powered cube.
The spreadsheet is broken down, color coded, and organized for ease of use. It lists the cards by color, card type, and converted mana cost, with total numbers of each.
It contains 383 cards - 50 of each color, 50 artifacts, 36 gold cards and 47 land cards.
It is important to point out that I did not make this card list by myself. I pulled the list from various places around the net, most notably the carddrafting.com forums. All of the power cubes tended to have the same group of cards, so I have all of those staples in here, including the power 9. I used Magic's cube from the carddrafting.com forums as my basis, then modified the list to my own liking. I replaced and added several of my own card choices to the list.
