The Eager Cubs you can get by chance from Cub Training are pretty boring. I have 98 (245 uses) total, and it is very rare I will use them at all. There is one lion in my pride with an eager cub decor.

I think it would be really interesting to, at a rare and random chance, get an eager cub with either the base of the cub that subsequently earned the Eager Cub.
Example: Eager Cub [Dikela], Eager Cub [Decennial]

I would love to put an Eager Cub [Fuchsia] on one of my Fuchsia lionesses.
