Sandshrew is a cool thing, but he's not really that durable and he can't really do that much outside of Spin- he can make hefty dents in the birds and Magmortar with prediction, but has trouble taking unresisted hits- Swellow 2HKOs 252/252 +ve with Facade. Lack of recovery and vulnerable to all hazards (though he resists SR, which is more than can be said for Cryogonal and Torkoal).
That said, even uninvested, STAB EQ hurts, so he probably isn't that bad, and he's at least got an immunity to switch in, albeit an uncommon one outside of Thunder Wave. Wartortle is still viable though since he can at least go for Burn hax and can guarantee a Spin via Foresight.
