W/B Grindy Midrange Control @ Pauper - Pestilence & Lifegain (Pauper) [Revision 4]

Copied this list from a www.mtggoldfish.com decklist, but cannot find the link anymore

The idea of this deck is the following:

1. Keep early threats of the opponent in check (Duress, Disfigure, Chainer's Edict) and build up blockers and hopefully additional life (Thraben Inspector, Wall of Hope, Lone Missionary, Aven Riftwatcher, Kor Skyfisher)
2. Get to Pestilence mana and play one. If this takes very long, hopefully have a Prismatic Strands out (which in most cases is almost a complete fog as well as being able to protect you somewhat from burn decks)
3. Start wiping the board of smaller creatures, while drawing some cards (Night's Whisper, Thraben Inspector, Palace Sentinels) and leaving one of your creatures with toughness 3 or 4 alive
4. Get into a state where you can trade your life lost from Pestilence activations with life gained, while hopefully having a Guardian of the Guildpact down, which is unaffected by Pestilence (so you never have to sacrifice it)and can block almost anything on the ground
5. Repeat 4. until the opponent dies

The mana base is a bit slow (of 22 lands, 9 enter the battlefield tapped), which I still need to experiment with. The deck can make use of a lot of lands in the late game, for Pestilence activations and for casting the extra cards it draws.

The sideboard is completely untested.
