Harmony - Troop Symmetry

In my opinion, it's better than the canonical Ashan deer, although the use of Ent resources is too noticeable.

The Ent traces can be removed, but changing the unicorn to a deer still feels like a lateral move.
Right now, I think the Emerald Knight is the most decent option. It wouldn't be bad to have some kind of beast, but which one?
Maybe a white tiger based on a Cerberus?
