Brawler Phantom Assassin
By The Punisher
With this build, you can start fighting and getting kills earlier than most carries can, shutting their farm down while increasing your advantage.
With a cheap core item list, Phantom Assassin can put the hurt on the enemy team before their carries can get big, and still keep up with them later in the game. You don't need to waste time farming a Battle Fury to murder people.
Once you have your core items, be aggressive, look for kills and leave nothing but blood spatters behind you.
