This is my first time making this build so pls leave a comment.
This build is to make tf have a strong att spd in mid game to push and during the late game to use his ulti to fly around ganking people with out getting CC'd.
This build also allow u to take down high hp n tanks quickly.

Pros:
-Able to push fast
-Able to gank
-Able to fight 1 on 1 with no sweat
-Able to kill tanks

Cons:
-Quite squishy
-Depends his stunts to kill
-Will be aimmed most of the time

Greater Seals of Alclarity: This rune gives you att spd in the starting to push and kill people fast
Greater Mark of Strenght: This gives you some att dmg in the starting so it could match with the att spd to kill enemy champion fast
Graeter Glyph of Celerity: This gives you to let the cool down of the 'pick a card' be refresh faster than usale as the skill is needed for a kill
Gretaer Quintessence of Strength: Again this allows you to kill fast in the early game

This masteires 21/0/9 it allows you to have a good dmg that is able to match with your att spd. i prefer this build because it allows me to hit the enemy champion painner in the early n mid game than the 9/0/21

Getting boots in the starting is quiet risky because of low health so better have a good lane parnter. If u get a boot in early game, u can run faster than the enemy champion so meaning that your 'pick a card' can have a higher chance of stunting/slowing enemy champions.
Sword of divid is to boost your att spd and if need, use it to kill a tank(not fully tank(mid game))
As u have your att spd, is time for u to get a dmg item, some thing lik a black cleaver, it gives att spd n dmg
after that i usally get a madred bloodrazor to have spd, att and to kill high hp enemy champions
Then i go for a phantom dancer to increase my att spd n movement spd allowing me to gank faster
then i go for a banshee veil in-case if i ulti to a location n the enemy champion tries to stunt me n make a run for it.

Must get:
-Flash(to escape)
Your choich:
-Ghost(to chase n run)
-exhaust(to slow people down)
-telepot(to continues ganking)
-ignite(to kill people)

This is my first time making a build so pls leave a comment :P
