>>31543043As a heads up, the Japanese name for Sand Rush is Sand Paddle. This is why Stoutland gets it. (doggie paddle) It's meant for things that can move through sand as quick as a fish swims through water.
In other words, count you blessings /vp/ because Garchomp is a sandshark, and by all means should get Sand Rush. The only reason it does not is the same reason it doesn't have Dragon Dance or learn Earthquake by levelup. Because they know perfectly well it would be terrifying.
