The "Phyrexian Poison" deck returns to an age-old victory path for defeating your opponents: poison! Infect your opponent with ten poison counters and you win the game. Putrefax can reach half that goal with one swing, while your Ichor Rats and Necropedes can make steady progress in the early game. The powerful infect ability ensures that your creatures' impact will be felt long after they're gone.

Use Corpse Cur to return your fallen creatures from the graveyard (like another Corpse Cur) to ensure you always have a creature on the battlefield. Worried about what to do if your opponent manages to stop you from attacking? Equip your creatures with Heavy Arbalest to poison your opponent directly, avoiding the combat phase altogether. Your reinforcements are immediately deadly with Hand of the Praetors, which gives your opponent a poison counter whenever you cast a creature with infect!

Find more cards to improve your deck in Scars of Mirrodin booster packs. Blight Mamba is deadly both on offense and defense, spreading poison with impunity. Protect all of your creatures with the powerful Asceticism, which stops your opponents from targeting them. Skithiryx, the Blight Dragon dominates the skies—an infectious 4/4 that will have your opponent dead in no time.
