Hazezon Tamar

When Hazezon Tamar enters the battlefield,
create X 1/1 Sand Warrior creature tokens that
are red, green, and white at the beginning of
your next upkeep, where X is the number of
lands you control at that time.
When Hazezon leaves the battlefield,
exile all Sand Warriors.
"I don't like sand. It's coarse, and rough,
and irritating, and it gets everywhere."
