Bisharp is a Steel and Dark type pokemon.
Have a Serperior,Darmanitan,Heatmor,Unfezant,Durant, and Throh. When you go to the champion, make sure you have a master ball to catch Zekrom and put him in your party by replacing Durant with Zekrom. I did this same exact thing and won. The champion has a Reshiram,Klinklang,Zoroark,Sigilyph, and i can't remember the others. Make sure have full restores and revives and lots of them. My only Pokemon i have are Zekrom,Serperior,Darmanitan,Heatmor,Unfezant, and Durant.
Unfezant is a Normal and Flying type pokemon.
Evolve Pawniard at Level 57 to get Bisharp
Serperior is a Grass type pokemon.
I used bisharp against the ghost and psychic elete four members, and my electross and serperior against the dark and fighting one.
