Conflux, released on February 6, 2009, continues the story of Shards of Alara as the isolated shards begin to collide, bringing chaos and cross-shard interactions. This set emphasizes five-color and multicolor strategies, introducing the Domain mechanic and expanding existing themes like Exalted, Unearth, and Devour. Notable cards include Knight of the Reliquary, Nicol Bolas, Planeswalker, Progenitus, and Path to Exile. With its emphasis on convergence and powerful multicolor spells, Conflux ramped up the complexity and synergy of the Alara block.
