fun build for those who want to meme climb in low elo
teemo mid corruption -> dorans liandrys -> ludens -> morello dark harvest/sorc (trans/manaflow) cdr boots cdr rune ultimate hunter try to snatch blues and get the first cloud drake
enjoy luzing as you spread around 4000 shrooms on the map and low elo doesnt know how to deal with it as you passively collect dark harvest stacks. grab sweepers and aggressively control ward. Focus ramps/bush have a good spread and dont concentrate on just one area. Move the shrooms around as you would wards were you supporting aggressively. Be aggressive early lane with your poke and just try to deny cs and cs yourself. They'll eventually send jungle after you, do a turn on shroom with blind ignite shroom and e and start stacking ultimate hunter!
[slayer-jinx-wink] no soul
once the aram mid starts and they start to retreat start shrooming their jungle at choke points. If you're feelin' lucky (heh) go ahead and sit on a shroom (my fav is by raptors) with ignite up as youve by now probably had a lead and jump people going to ward/sweeper.
once you have 40% cdr liandry dot + morello grievous wounds (I went void after, could go cap depending) and ultimate/cloud you literally run around spamming shrooms as they constantly come up. Half their team doesnt even buy sweepers and the ones who do are tilted off the planet at the others when they die.
you would think that this wouldnt work, it does. both my teams recently were losing all game and eventually were able to just clap people half dead from shrooms or collapse on them by accident. it really works against unorganized unstrategic players.
you need to keep the shrooms up and mana flow at first is an issue -- run around looking for the fruit blossoms in river. youll have control from shroom zoning and can take scuttles as well. prep dragon/rift as traps.
