Teemo Jungle
Not sure if this is the appropriate board, but didnt want to post this in GD and get tore a new one for "trolling with satan".
But anyhow, im trying to make Teemo Jungle a thing. I like playing "things that others consider hard/bad" and prove them wrong. I also like not using flash or ghost (cause im not a filthy casual) to make it "harder" for me, it helps my decision making. I.E.: Can i go into this fight and get out alive? Im currently at a 61% win rate with 45 games played, i know its not much, but it would be higher if i didnt have people AFKing when they died in lane 2 times from their own faults 5 minutes into the game.
So for Teemo jungle, theres several build paths you can go through with the little guy. But for most, my masteries and runes stay the same.
Runes: Marks: 9x Attackspeed. Seals: 9x Flat Armor. Glyphs: 4x Flat AP, 5x MR scaling. Quinns: 3x Flat AP
Masetries- 22-5-3 Getting all that damage in as possible. That extra movespeed helps you kite and run in your jungle faster in the early stages.
Heres some example builds, but of course builds can change during game.
Traditional AP Teemo.
May not seem like much, but with the 40% cdr, you can spam shroom the entire map, and with Torment of course, thats a decent chunk of HP. Why Twin shadows? Well most junglers have something to intiate with, teemo jungle, is all about catching people out. Someone hits your shrooms nearby? Hit twin shadows to make sure they stay slowed, and are revealed for your team to catch up.
HP% Teemo. True Satan.
This build may seem laughable and unbalanced. But with teemo, its terror. Ive had a ton of success building bork AND torment on teemo. Plus having the devourer for infinite stacks helps out your late game damage. Not to mention with Bork, you can solo dragon early on if you rush it, very easily.
AD Teemo.
This one im still playing with. But it all revolves around the Hurricane. The Hurricane will apply your AD obviously, the Devourer damage + stacks, the bork on hit HP %, plus the Frozen Mallet debuff to slow EVERYONE all at once, its great in the middle of a team fight doing hp %, ad AND ap damage, plus slowing them, and lifestealing all at once.
Tankmo.
/
This build, is by far my favorite. People will be all over you. "Kill teemo".... Jokes on them half way through the fight they notice your tankmo. EVERYONE especially in low elo, hates teemo, and will focus you no matter what, so get in the middle of a fight, throw your bork and Q on their carry, and aggervate the piss outa them. Take the HG if they got champs such as LB/Brand/Vi so you can hourglass through it and stay safe. Take Thorn if your vs champs such as Yi or Tryn. Its a troll build, but it works wonders if you can piss off the enemy team enough to focus you.
Anyhow, this is how im doing with him so far. Let me know your thoughts, or what you would do differently (other than saying no to teemo lol).
----------EDIT----------
So few things i figured i'd try.
Switch up runes, Hybrid Marks with AS quinns, or Lifesteal Quinns with AS marks. I like the AS so i can get the smite buff from golem, and then proceed to stun lock + blind the red buff and blue buff, to take minimal damage.
Find a few "Better optimized builds" Such as subbing in a Void Staff. I never really figured (its obvious but im too close minded to see it) that the HP % items do get a massive reduction on resistance, so they need PEN to work. So i need to add in LW/BC/Void staff into those builds, such as the following for "improved"? builds.
AP-
or 
Hp% -
? Weird build not too sure.
AD/Brute-

Also, i do realize, that teemo is "not that great for ganking, or team fights".
But in truth, its all situational, or as someone said below, the stars have to align for you to pick teemo jungle as a good pick, with a CC mid, tanky top, and a tanky support. But in truth, thats the meta, Assassin mid mostly, with tanky or CC whore supports (annie, naut, morg, leona, thresh), and a brute-ish top.
Teemo excels at map control. With some CDR and the blue buff (some mids dont need it anymore), you can easily drop 10-15 shrooms around the baron and or dragon pit. Control their jungle if you get ahead, split push with their jungle shroomed, giving you a safe way to get out, and easily let your team catch someone out trying to come after you. Even better, if the enemy team has a dumb carry who likes to lead the pack and set off your shrooms, they will be even easier to kill, or their team will spend more time trying to sweep your shrooms, than grouping, letting you maneuver around them for easy pick offs.
I guess you could say, you would have to be skilled to do it, and have a great team to communicate with, and wouldnt suggest it for most solo Q situations. I tend to tell a joke, lighten up the mood, see how everyone is, if their chatty and seem cool, ill do teemo jungle and reassure them im not trolling, and we do well. If their all silent types who pick riven top (COUGH FUCKING WHORE), ill just stay with Noc or Xin.
do it infinitely better. if your looking to make things harder on yourself you shouldn't play a team game.
His pull + Q + Bleed combo is great with my poison, tons of damage over time, even if they flash, we got the kill without chasing.
Fid was able to Silence, then Fear them, while i was able to position myself behind them, damaging them the whole time, plus with red buff, he was able to cast his Drain for free damage.
Oh god this lane. Braum alone won it. His passive made my ganks so easy since im ranged, they couldnt escape, ever. Ashe was just able to slow them even more so they couldnt escape us. Their bot lane NEVER went into their bushes, or went past river.
