but what if i build this shit on teemo what is your answer

Maw of malmortius, deaths dance, youmoos, cleaver, randuins, merc treads
Thats the world's dumbest fucking teemo build. Its a confused build that tries to incorporate tank (btw mages will blow you the fuck up because no mr mr. "Tank teemo"), on hit, and sustain. What you really end up with is a near zero damage teemo that has enough hp to survive maybe a few more seconds but not enough to actually tank much.
Wits end sucks dick because a huge portion of it is dependent upon prior stacking which bruisers like udyr can safely pull off with their innate AS and tank steroids (teemo has a very unreliable and sometimes dangerous AS steroid and absolutely no tank steroid whatsoever). The randuins will gimp teemo's attack speed, and the powerful four second slow passive in conjunction with youmoos ghostblade active will allow pantheon to negate frozen mallets kiting ability. Even if you swapped wits end for an ad item, your E will ensure that pantheon always gets to take advantage of maw's lifeline.
It's a cavalcade of buttfuckery and teemo is in the front.
