Okay so this is my first build, go easy please :P. I recently started playing twisted and i sore that he can be really op if he gets the chance to get items,So a couple of tips about twisted is when you start of (on a 3v3 match) it is better to go with someone or if u really a hang of it then you can go alone on top. The doran's blade will give you some health and extra damage at start. I take Pick a Card as the first skill.
Remember if you have some tanks in your team you need to stun the enemy and leave the tanks to do the job.

So the full items you can see on top but what do you buy in between? :O
Well after the doran's blade i usualy get the dagger which then turns into Berserker's Greaves then you should quickly get zeal and then the first phantom dancer.
After that, you should save some money for the B.F Sword and then buy the next two items for the infinity edge.

By now you should get some kills, if ur running away pick a card and get the gold/yellow card and stun the enemy then run but to be fair if u have shoes and two phantom dancers running away is not a problem :)

But back to the items after the infinity edge get zeal and again the phantom dancer, oh and also after the first dancer sell the doran's blade (or after as you wish). Now it is crucial that you take the Vampiric Scepter ( or sooner!!) with that you will regain alot of health due to the speed of the phantom dancers, now again saving time another B.F sword you need for extra damage and as another item for the Bloodhtirster. If you do get that far (talking 5v5 wise) then the last item you need is the black cleaver. My mate in a 5v5 killed all 5 on his own when protecting the middle inhibitor :O and he ended up having 23 kills, but thats another story. If you want to know what skill 'combos' you need to use Read on :)

I will try to make this as simple as i can :P:

1. Pick a Card - gold
2. Willcards (make sure the middle card hits the enemy you just stunned)
3. The passive E will do the job if you have the dancers :)

So that is just one sequence if you want to solo someone,

If you want to run away: Pick a Card - Gold hit and run :D

If your chasing someone then you should get either the red or gold card but i would recommend the red then the gold because with that combination your enemy is slowed (gets hit) then stunned and eventually (if he doesn't have 4k hp) dies.

Another important thing you need to know is when you run out of mana use the blue card and hit a minion or champion with it to regain some mana quickly.

So that would be all i guess for my first build. ( i decided not to do the runes because i am not really good with runes so i have not got a clue :L)

Hope i Helped,
