Astro Spin is the key. I have got ~10k rubies and in turn 2000+ claws with $7 purchase for astro spin in 24 hrs. (I did not even played that long to get these resources)
Now my feeling is I have way too much claws and don't feel like using them as it felt wasting time. The animation is too slow and repetitive, I get bored quickly when I have feel obligated to claw with 1k+ claws.
Now I still have about 1k claws left but just being lazy to use them as I have completed all planets.
