Rabbit's Foot you can get from the artifact collection ”Power of Love” it's not the actual artifact but when you complete the collection it's one of the items that comes with the collection (along with coins and energy, etc).

It completely restores your energy and increases your max energy by 10 permanently. It's a very useful energy boost.

Some of the items may only be avaible from high ranks but that doesn't mean you can't ask your friends for them or put them on your wishlist telling people you want them.

And usually with certain seasonal events like Spring/Halloween/Christmas one of the rewards is a new totem that sits somewhere on the map. If you look on the Totems page, you'll see more about them.
