After you buy your first item you MUST go to second bush (next to their turret) and ambush the enemy toplaner. If you are successful he will play defensively and try to set up ganks for their jungler. Try to farm a lot and get as much minions as you can to buy ward and to get to full build faster. If you notice that you are ganked,DONT PANIC. Use Decisive Strike and silence the enemy jungler and reach your turret than play defensively for 2-3 minutes or if you think that jungler is no longer threat. If you must play defensively try to farm and set ganks for your jungler and take advantage in the lane.

PROS
1.No mana needed
2.Massive advantage early-game
3.Can not be easily ganked
4.Massive health regen
5.Good escape mechanism

CONS
1.Low dmg late game if you build full tank
2.Very difficult to play if you are not fed

You can combine Sunfire cape,Decisive Strike and Judgement to farm very fast large minion waves.

If there is a teamfight brewing,charge in head on first (you have hp and armor/mr). Your teammates will do it too and you will most likely die but your team will win teamfight and you will get 5 assists or how much enemies will be in teamfight but all for sake of teamwork. If you team up with high DPS champ (like Fiora or Xin Zhao) try to set them kills because they need to get more fet than you.
