I'm not talking about the anime, I'm talking about the visual novel, and she does use it in the VN. Saber and Shirou use it (the active state) to counter Enuma Elish and the shadow curse, respectively.

Also, you're probably mistaking the legendary Land of Avalon and the Noble Phantasm Avalon. The Noble Phantasm is just a protection, while the Land of Avalon is where Saber was headed to after Bedivere threw Excalibur in the lake.
