MTG Salvation

I run revised duals, fetches, and shocks in my Pauper cube and everyone I have talked to agrees it works better that way for us. It really gives you the chance to focus on enjoying the cards within your rarity restriction without people feeling handicapped by slow/unreliable mana. I think it increases the diversity of decks that are viable and is a vital part of appreciating the value of many cards (my cube is Pauper so Wood Elves, Farseek, land cyclers, Wild Nacatl and Kird Ape, Adventuring Gear, and many more). It also helps sell the format to people used to play powered cubes.
