Playing with your life (Orzhov)

The Orzhov are the Church of deals - and the main deal of this deck is your opponents' life totals! This deck aims to extort and lifelink their totals into oblivion while defending your own. Sorin helps you along by literally controlling one of your opponents during their turn.

Part of my 10 Guild EDH Experiment:
One deck per guild, only legal cards are:
-Ravnica and Return To Ravnica Block, plus Innistrad utility land, checkland, one walker, and any timeshifted/core set cards that bear the guild's mechanic
-Must align based on watermarks (no cross guild spells)
-Must contain both guild leaders and both guild champions so the player may choose whichever they prefer as general
-Must include all land and artifact cycles
-No card (outside of Pillar of Paruns and Command Tower) may be shared across guilds
-Each deck should focus on a particular play style
