Even though the Phyrexian takeover of Mirrodin is at hand, not everyone has fallen prey to the Phyrexian contagion. That's where you come in! With the "Ravaging Swarm" deck, you'll spread the disease to anyone who would still dare to oppose you.

The deck starts off as quickly as possible, preferably with early Glistener Elves andBlighted Agents on the first couple of turns. Since they have infect, each time they deal damage to your opponent, that player gets a poison counter—and since it takes only ten poison counters for a player to lose the game, you're well on your way to victory!

A number of cards in the deck, such as Phyrexian Swarmlord and Mycosynth Fiend, get powered up if your opponent is poisoned. Even a little disease pays big dividends! And cards such as Viral Drake and Plaguemaw Beast let you proliferate, which increases the number of poison counters your opponent has, one . . . by . . . one. Once the infestation takes hold, there's no cure.

After you've played the deck a few times, you'll want to put your own stamp on it. Look for cards that pump up your infect creatures' power. Spells such as the Magic2011 core set card Giant Growth are a good way to do that, as are Equipment like the Mirrodin Besieged card Sword of Feast and Famine. Alternately, planeswalkers such as the core set's Jace Belerenare a great way to take advantage of the proliferate abilities in the deck, since proliferate works on loyalty counters too.
