I never push trophies. when i maxed my defenses, valks, and healers for th9, i pushed masters to get the 1k gems, but then i immidiatley dropped back down to like gold 1 or 2 in order to far resources to max my walls and lab. even after a couple of succesful attacks, i try to drop down right after so people cant steal my dark elixir. heroes imma get 25 both then bounce out to th10.
