This unique build will give you a different view of TF in the middlelane and in teamfights. Instead of relying more in sudden burst attacks using his combo, adding attack speed with Guisno's Rageblade will give him a greater chance of winning. Using the usual W-Q combo and a hit of his E, a kill isn't guaranteed. But having an advantage aside his burst W-Q, E is quite helpful too. Increasing his attack speded can make him an adr or apparently an APR(Ability Power Ranged). This can be quite helpful in teamfights rather than running and waiting for you cooldowns. Try it, it's effective.
