Your saying he could've used sand tsunami, sensor sand...
his sensor sand was used to find Muu..he didnt use it to find the clam
and sand tsunami, he started off with that and the avoided it easily. I mean, if what you all are saying about kill him instantly, why didnt gaara just do that after the mizu escaped? he couldve just caught him again just as easily right? especially since he had help, and especially since he was in the desert. You say, "Well he had to protect ppl so he was handicapped." They placed him in a desert, with another kage to ake up for that handicap and he still barely won.
