When they rework Shaco, I hope that they make his passive steal gold after a kill.
The definition of a snowball type champion is imo Shaco. The worst game I ever played was against a Shaco that bought sword of the Occult and Mejais, fully stacked both by 20 minutes. I'll never forget that game lol. But I thought it would be a good snowball feature for Shaco once he is reworked.
