Double Controller:

Double Controller is a team composition that uses two Controller agents to layer smoke, wall, and area-denial utility for stronger site control and post-plant play.

It is used to block multiple sightlines at once, make retakes harder, and create safer spaces for a team to take or hold ground. The extra smoke and zone control can also let a team split the map more effectively, since one Controller can cover the main push while the other supports a different lane or delays a rotation. In practice, a team might pair Omen with Viper on a map like Breeze so one player can smoke key angles while the other uses a wall to cut off long-range defenders and slow a retake.
