Potential annoying build URF for Teemo

Movement Speed Turret Tanker Teemo (MSTx3, so I call him Anti-Backrow Teemo...which is fitting if you know how to use him). , Frost Queen's Claim for the slow, Youmoo's Ghostblade for the speed and AS, Death's Dance for the Lifesteal, Dead Man's Chest for the passive speed and that one basic attack for damage, BotRK for speed steal (anyone who wants to run from you DEFINITELY CANNOT), and Warmog's Armor for the passive heal. You get only 160 AD, +40% AS, and 50 AP, as well as 1300 Health, 200% Health Regen, +10% Lifesteal, 50 Armor, and +2 gold/10 secs (other than mana-related and cooldown-related stats which are unimportant); but when using Ghost, Heal, YG, and DMC from spawn with a Homeguard buff and Teemo's max W, you can go around 750 MS without reliable Quints. And you can keep it around 600-something without Homeguard and constant Heal. I went Death's Dance because his AD is more reliable for lifesteal than AP. He's going to be over 3000 Health at the end of the game, and he's going to take pretty much no damage from turrets, so I put Warmog's on him for that reason. I just played this build, and boy I was dodging so many skillshots...luckily they had a Jinx, which made things a little easier until they thought I was trolling (and yet we won~). So try this out if you get the chance to Teemo before ARURF is over, and whatever you do pay attention to skillshots. Also pay attention to Evelynn, because even though you're faster than her you don't have MR. EDIT: Also, if you have AS Marks and Quints you can reliably get up to 2.5 AS. Not sure if it does this already without them, just thought to let you all know I got to 2.5 in the game I tried it on.
