It's been over two months since the release of last Magic: The Gathering set, "The Brothers' War." There, the original Magic plane of Dominaria was under attack by one of the most evil forces in the Multiverse. Now, it's time to head to the plane behind the invasion, and take on the enemy in their home turf.

Welcome to "Phyrexia: All Will Be One." Unlike the relatively peaceful blue skies and natural oases of Dominaria, the plane of New Phyrexia is a twisted fever dream--one full of death, decay, and metal monstrosities held together by tissue and tendon. At the helm is the loathsome leader, the "Mother of Machines": Elesh Norn.

Phyrexia: All Will Be One (ONE) is a large set, bringing 271 new cards into rotation. Both flavorfully and mechanically, it is a much different landscape than the previous two Dominaria-based sets we played with. To tackle your prerelease, or get a head start on building new decks for constructed, you'll want to have an understanding of everything going on in ONE.
