There are so many strategies my friend, I can't even begin...this is by far the easiest incarnation of Rugal IMO. Before he takes his coat off, just jump kick him to death. He'll either block or eat your jump kick, then regardless of what happens, walk up and just grab him. You can also do the slow projectile+dashing special trick. Throw a slow projectile, if he tries to sidestep, wait right before his evasion tactic is over, then perform a rushing special attack (Burning Knuckles etc). After he takes his coat off, same strategies, but now you can't hang in air as often because of the "Genocide Cutter". Limit your jumping by half, and you'll be just fine. He will try to bounce some of the projectiles back, but usually not that many.
