hey this is my build for twisted fate. here is some tips and why iv'e chosen the items i have chosen: i don't use wild cards because it uses to much mana. Combinig you 4th card with pick a card can give a high amount of damage ispeacialy if you use the blue card. When you use you ultimate remember to have you 4th card and rellow card ready that will help get a easier kill and a good amount of damage. sword of divine is also very good against armor cahmpion or dodge champions like jax and rammus (remember to activate it)
madred's bloodrazor is good against tanks like mundo, it takes 2% of your targets maximum hp as extra damage, so tanks aren't realy the biggest problem for twisted fate. iv'e chosen frozen mallet as the last item because he is very low on hp wich makes him an easy target in late game but he is very good at pushing in early game, so frozen mallet is very important.
twisted fate's main damage is because of hes attack speed he har some damage but the attack speed those the trick.
enjoy :D
