A few weeks ago I picked up an old copy of, The Official Deckbuilders’ Guide, a sanctioned MTG book from 1997. While the book is basically a collection of 120 Deck lists, rather than a deck building tutor, it does contain an interesting mix of ‘themes’ along with deck comments.
I noticed that one chapter of deck lists dealt with commons only decks, constructed with cards exclusively from Fifth Edition, and using the 10 possible dual-colour combinations. This got me re-interested in Pauper.
For those not familiar with the format, it is basically a commons-only affair.
