basically uhhhhhh just try kaliedastone teemo. think about it, pretty much all the keystones are good on teemo. people have run electrocute, dark harvest, hail of blades, aery, press the attack, and grasp. on top of that, lethal tempo, fleet footwork, conqueror, predator, comet, phase rush, and glacial augment are all perfectly fine too!

uhh I go ravenous hunter for the healing, cheap shot is good cuz u proc it with auto Q cuz ur poison will proc it after you q. I think dematerializer is good cuz it helps with teemos doodoo waveclear. i usually use them on the melee and cannons. being able to clear the minions faster with your autos means you can save your shrooms for anything else; area denial, all inning if you can proc it on the wave, baiting, vision, etc.
