The Phyrexian infection has spread to encompass all the colors of Magic. Like any aggressive green-white deck, the "Path of Blight" deck deploys cheap creatures to the table and then uses combat tricks to ensure that your cards trump theirs. The difference is that since all your creatures have infect, they need to deal only 10 damage to your opponent to ensure your victory! If you can't get the last few poison counters using your creatures, Decimator Web can seal your victory once and for all.

Start out by casting Blight Mamba or Plague Myr on your second turn, and keep up the pressure by continuing to cast creatures like Rot Wolf and Priests of Norn. Your deck has creatures at a variety of mana costs, so you'll be able to make use of all of your mana on almost every turn.

Use your spells to make sure that your creatures can keep getting through to deal damage to your opponent. Clear blockers out of the way with a Banishment Decree, especially if it lets you push through the massive Phyrexian Hydra. If you see your opponent is planning to "chump block," use Mighty Leap to send your creatures to the air before blocking, or wait for the block to happen and then use Unnatural Predation to make that blocker less effective.

Of course, other Mirrodin Besieged cards can help you customize your deck. Creeping Corrosion, a sorcery that destroys all artifacts, is the perfect answer to any sort of artifact-based strategy your opponent may be using. And of course, the ultimate fighting machine in any infect deck is Blightsteel Colossus, an 11/11 creature with trample and infect that's capable of taking down your opponent with a single attack!
