By enchanting Razorkin Needlehead with Corrupted Conscience, we transform a humble tormentor into a lethal engine of infect, turning every single point of damage it deals directly into poison counters. We then cast Windfall to flood everyone's hands with fresh cards, which immediately triggers Razorkin Needlehead's punishing ability for every card each opponent draws. Because the damage is dealt in the form of infect thanks to Corrupted Conscience, that massive burst of card-drawing translates instantly into ten or more poison counters, causing each opponent to lose the game on the spot.
