Phyrexia: All Will Be One is a Magic: The Gathering set concluding the Phyrexian invasion storyline on New Phyrexia, as the multiverse's most feared faction pushes toward total domination. The set introduced the toxic and oil counter mechanics, letting decks poison opponents out of the game entirely as an alternate win condition. Its compleated planeswalkers, twisted by Phyrexian corruption, remain some of the story's most striking cards.
