Good Magical Beasts?

[Necroticplague]

O.k, simple situation here. Got a Planar Shepard I plan on building. For the plane I've selected, I decided to go with the Plane of Shadow. Thanks to the Shadow template, and the last sentence of the second paragraph. this means pretty much any Animal or Magical beast is a fair choice for my Wildshaping. However, trying to think of anything useful, I run into the problem where most animals have little interesting traits, outside of basics like movement and being beefy. The character is also a MoMF, so they have the Extraordinary abilities, if it helps.

Cyrohydras are the goto for frozen wildshape, so they should work for you too (but you have the option of Pyrohydra and normal hydra if you want to as well).
