Modern Horizons 3 is a Magic: The Gathering set designed specifically for the Modern format, delivering a fresh wave of format-defining cards, powerful reprints, and new archetype support built purely for competitive constructed play. Like its predecessors, it skips Standard legality to focus entirely on shaking up Modern, Legacy, and Commander metagames. Its release reshuffled tier lists across multiple eternal formats within weeks.
