i almost forgot, items like sword of occult that pick up stacks and give big bonuses that are lost upon death are not good choices for tf and other extremely squishy champs. it doesnt matter how good you are as tf you will most likely get caught in a ridiculously long stun or slow, which leads to being torn apart in a mere two seconds, which leads to a loss of a third of your stacks (and in the case of bloodthirster, all of them).

fail build. same reasons are Tinaby. also, my pet peeve, sword of divine pretty much sucks, 100 magic damage every fourth attack-pitiful. 30, undodgeable, armor pen for 5 seconds-pitiful just get last whisper for 40 armor pen. your attack speed should be as close to 2.5 as you can get, which makes 5 seconds of undodgeable attacks pretty much worthless

No explanation for any choice, bad masteries (improved rally when not taking the spell ??? idem for Revive ???), bad runes (if you want damage, get armor penetration and AD/lvl 18, not flat AD), bad summoner spells (teleport with TF ?!?)

Also you selected 12 items, you should let only 6 appear in the section so we can see stats and give the possible switches in the explanation of the build (but you don't have any explanation).
