Xanathar

Xanathar is a Dimir (blue-black) Commander deck built around controlling the table and generating value through evasive creature attacks. Its core plan is to land Xanathar, Guild Kingpin, protect it with counters and removal, and gradually take over the game while disrupting opponents.

Key synergies revolve around card-draw-on-combat effects like Reconnaissance Mission, Bident of Thassa, and Kindred Discovery, which reward attacking with creatures and help keep your hand full. The deck backs that up with a strong control package—Counterspell, Swan Song, Arcane Denial, Cyclonic Rift, Damnation, Toxic Deluge, and efficient spot removal—to slow opponents while you build advantage.

It generally wins by grinding out value, controlling opposing threats, and attacking with its board over time, with unblockable/evasive support like Rogue’s Passage and Access Tunnel helping key creatures connect. Overall, it plays like a midrange-control Dimir deck that leverages steady card advantage and disruption to dominate the late game.
