I don't understand why you need boots first as mf. Could you please elaborate? Also, impure shots can give you pickaxe damage if you level it early.

Techonic, i want to meet you in person so we can make babies because this guide just rocked my world. Add me in game. IGN: ddtTrigger haha

Keep in mind the better you are at last hitting the fast you get these items. Getting FM for me as a 3rd item is not a problem for me because I get my items fairly fast, but if it doesn't work out FM before bloodthirster will work too. I just recommend getting bloodthirster as the second item is because in the process of getting it you gain AD from the BF and that already make you out damage your opponent plus the fact that it stacks works really well when you get the time to stack your bloodthirster early game. In late game it is harder to stack it because you find yourself in a lot of team battles not farming.

Personally I start with AD en AS (base mov.speed is already 410 incl. strut). In 10 minuten (maybe 3/4-0 kills) I have something like 140AD and 1.250AS. Farming minions gives a lot of money tho (Make it Rain incl AD is probably best spell from all champs to get the minions that fast). After a couple of kills, been feeded and some buffs+neutral monsters I always get my Infinity Edge. Yesterday our team was loosing. All our turrets were down, only nexus was still up. I aced them (played with pro eve) then we pushed. Suddently they surrendered. I had 2600HP, 280AD and 1560 AS (470movement). Evelyn same ammount (even more) AD and AS. GG.
All I want to say with this: Frozen mallet is a good item for MF

and i suggest starting with phage for your FM that way at the start you already have the benefit of chasing down your enemies

Personally, I think your rune choice could be changed to utilize MF more. Grab Mana Regen on Yellow, because Blue Tier 3 is the same as Yellow Tier 2. Blue could be something different to make it Tier 3. Build seems generic and would work, not gonna vote because it is hard to decide if I like this or not.
