Jack Rowe and Dan Rodden completed the scoring to leave assistant boss David Hamlet purring over the gamble to move Herz.
"We have been on a upward curve in the last few games and we found our shooting boots here," Hamlet said.
"Michael has proved a real threat since moving to striker. He has given us an outlet as a target man.
"He will not be going back in goal in a hurry."
Struggling FC Cosmos, who replied through Rafi Newman, are still yet to win this season.
