Lucky dog. I'm up to 9 decorations and still don't have one that increases my shares on reset. Several of my are pretty pointless: decrease private show spawn time (by 12 seconds... seems like they were spawning pretty darn fast without that). Increase booster time, (like I haven't even bothered using any) +3.2x tapping power (which is pretty inconsequential)
And it'll take me ~12k shares to discover my next one.
Oh, and P.S. private show clicking >>>> Mega coin. Private shows = keys = chests = gems = x2 shares on reset.
