Advice alone isn't going to cut it, you need the abilities to implement it. In my very first karate point-fight (a pretty tame format when compared to MMA), my coach would scream at me "Counter! Counter!! but the other guy was simply too strong an opponent. Any coach can give you good advice and a clever gameplan and superior tactics can win you fights, always provided you have the required physical skills.
I've sometimes wondered if dojos didn't create their own egregores. It's weird. For years we used to practice in a small highschool gym right after a senior citizens ballroom dancing class but once the room filled with karatekas, it became a martial arts hotspot with extremely intense vibes. Maybe a martial god can inspire you, not just motivate you, but drive you to the point of obsession when practicing. Blind berserker rage may work on the streets against multiple opponents but the best competition fighters I've ever seen always had this ice-cold, impersonal fury in them, well-controlled but explosive.
There are many misconceptions about fighting. Fighting is messy, it never goes according to plan. And it's never about the glory, rather about surviving and perhaps winning. As General Patton once said: "No bastard ever won a war by dying for his country. He won it by making the other poor dumb bastard die for his country." And that may include feints, trickery, or ambushes. Come to think of it, invoking Hermes besides Mars might be a good idea when it comes to martial arts.
