If sandshrew is going for an assassin build I can think of maybe 10 moves beneficial to her growth 1. Earthquake (this is the only move that i will recommend for her despite it not what I would class as an assassin class move) 2. Agility 3.sandstorm 4. Double team 5.dig 6.sword dance 7.iron tail 8.safeguard 9. Protect 10. Endure But there's also focus punch, shadow claw, bulk up, stealth rock, rock tomb, rock slide, and poison jab to recommend also.
