Background
Duke Leto Atreides is the statesman of the roster. His Landsraad Popularity makes every Landsraad board space cost 1 Solari less — the High Council, the Swordmaster, the Mentat, Rally Troops, all discounted. His Signet Ring turns 1 spice into an Influence step with any faction where an opponent outranks you — diplomacy aimed precisely where you're losing.
Leto rewards a political, infrastructure-first game: cheap Council seat, cheap third Agent, and a signet that quietly erodes every Influence lead your rivals build.
