When Hazezon leaves the battlefield, exile all Sand Warriors.

At the beginning of your upkeep, if Hazezon Tamar entered the battlefield since the beginning of your last upkeep, put a 1/1 red, green, and white Sand Warrior creature token onto the battlefield for each land you control. Those creatures have "When a permanent named Hazezon Tamar isn't on the battlefield, exile this creature."
