    This deck has a lot to do with color changing.  Phyrexian Bloodstock's

ability reads: when Phyrexian Bloodstock leaves play, destroy target white

creature.  So, with Tidal Visionary, you can destroy any of your opponents'

creatures by changing their color to white.  The combo of Jaded Response and

Vodalian Mystic work along the same lines.  Sisay's Ingenuity acts as a

backup, should your Tidal Visionary all die.  Tainted Well can change any of

your opponents' lands into swamps, so that you are insured swampwalk with

Lost Soul and Plague Beetle. Add Scavenged Weaponry to either of those

creatures, plus play a Shriek of Dread, or some Boomerang, or sacrifice a

Seal of Doom, and your oppenent(s) will be defenseless (unless they happen to

have a lot of Counterspell, and you're out of Jaded Response).  Other cards

to add to make it better are: Vile Consumption, Viscous Hunger, Last Caress,

and Drain Life.
