I like your guide, but the only problem i have in the squishy guide is summon aery. The problem i have is that when teemo uses that rune, his shrooms proc it, and no matter where he is, is reveals his location on the map, and the farther away he is, the longer it takes before he can use it. Its very good early game, and i can see why you would take it against squishies, but comet is almost as good, and comet comes with the benefit in that when shrooms hit, comet will land, and the enemies will be slowed and be unable to run. Also, shrooms may hit multiple enemies, so comet may hit more than one, whilst aery is limited to one.

While i say that, my personal teemo build is a glacial augment into nashors/liandrys, but that sucks against tanks and bruisers, so i'll probably adapt your first build as i've needed something against them.

Quick question, will that build work against a nasus that rushes E? i main teemo and nasus, and whenever i pick nasus, i get countered by teemo a lot, so i usually rush my e to counter the teemo, so i wanna know if your build will be a viable counter to that strategy. (yes it fks up my stacks, but i atleast have some farm, and once i get some cdr, i can stack up later on.)
