If you aren't playing lightning main (or even earth depending if you all of the 3 ninjas from the hidden cloud treasure), you won't see any benefit from pulling from the hidden cloud treasure. You can either pull try to pull han, roshi, super rares from kage treasure or even save for the GNW treasure which most likely be out next year.

Currently, we are missing two treasures compared to what China has, which are hidden cloud and GNW. Edo guy? Do you mean 8 eights guy?
