We study the possibility to replace the anti-neutrino run of a long baseline neutrino oscillation experiment with anti-neutrinos from muon decay at rest. The low energy of these neutrinos allows the use of inverse beta decay for detection in a Gadolinium-doped water Cerenkov detector. We show that this approach yields a factor of five times larger anti-neutrino event sample. The resulting discovery reaches in $\theta_{13}$, the mass hierarchy and leptonic CP violation are compared with those from a conventional superbeam experiment with combined neutrino and anti-neutrino running. We find that this approach yields a greatly improved reach for CP violation and $\theta_{13}$, while leaving the ability to measure the mass hierarchy intact.
