I use this build every time i play TF its very good for middle lane. You will become op later on in higher levels but the first few levels may be a struggle just play defensibly and poke with gold card and stacked deck. if you are struggling after you buy stinger buy chain vest and after you have finished your trinity force buy a guardian angel and don't build and infinity edge or build a banshee's veil instead its up to you both work well. if u can get fed quite nicely you wont need to use guardian angel or banshee's veil. Summoner spells use whatever you like using i use flash and heal because flash is very useful on escaping and heal is just handy for when you are in a tricky place and for helping your team out.

I play ad TF buy red card against minions gold card against champs and blue card on a turret or when u need mana. But by all means if the champ is around their minions try and slap a red card on him/her and if they start to run slap it on the minion closest to them so you still damage them. when u hit higher levels and are in group fights and you don't mind letting your team getting a kill stun one champ and move on to the next and use a blue card on the other. if you can always try and stun the champ that would deal the most damage. Your destiny move is amazing don't be afraid to use it loads its good for seeing if enemy are at baron random champs in jungle and picking off champs that escaped with low health. when you do hit around about level 15 you may end up taking alot of kills as the speed and damage you will be dishing out will be lovely just try not to upset your team by taking all the group kills
