Lol, maybe you mean luck on the road?
well, "Luck on the Road" is almost a given here (without it, what "Trophies" are we talking about?) - based on personal experience: I also believe that "Trophies" are more suitable for secondary heroes, because the bonus from them is too weak (I developed 3-4 secondary heroes with this skill - unfortunately, the results of "Luck on the Road" are much more noticeable).
