I hate the Saurus...

One strategy for dealing with the Saurus in Total War: Warhammer 3 could be to focus on attacking them with ranged units from a distance, such as archers or artillery, to whittle down their numbers before engaging in close combat. Another option could be to use cavalry to quickly flank and attack their weaker sides or rear. Additionally, using spells or abilities that can weaken their armor or morale could be effective in breaking their formations and making them vulnerable to attack. It's important to also consider the terrain and positioning of your units to gain a tactical advantage.
