Shaco clone with Eye of the Equinox or Face of the mountain procs on both himself and on the clone
So when you create your clone, he applies on hit effects, which is exactly what the eye/face is. Its an execute on hit. When you have a clone attack minions you can get bonus gold for yourself and heal the clone with your own executions,since usually the clone will be the closest hero to you. I highly doubt this was intentional, since it makes early tower dives on shaco almost guaranteed (as a support) since you can execute and heal from the minions, while your AD does all of the damage. This is especially a problem late game, because if you have Eye, you have 8 stacks every 50 some seconds that you can use at once for tower dives.
Again, I do not know if this is intentional, but it seems a little bit busted
