A year ago, in a Khans of Tarkir Standard dominated by many of the same decks (Jeskai, Abzan, UBx Control) and cards (Siege Rhino, Mantis Rider, Wingmate Roc), there were two decks that cost less than $115 (UW Heroic and Mono-Red Aggro) and only a single deck that cost more than $400 (Abzan Midrange)
