I think that Ignite and Flash are nice for teemo. The flash can really save him from some sticky sitations and his W ability goes well with it becuase after you flash then u can get away even quicker. The Ignite i think is helpfull becuase in the lane he can add that extra 50ish damage to kill someone, and along with his E it is quite scary how much damage, you may get away from the inital gank with about 100 hp but dammmm ur dead just to let you know :D

To be honest i think that these runes make your early game where teemo shine really stand out. The armor pen reds can really dominate top lane and sometimes even bot lane for those tanky DPS. The magic resist yellows can honestly save your life becuase sicne teemo is offered to go mid alot he can tank more shots from that mage caster who takes mid on there team. The blues are to make you more durable. And the quents are to make your hp mroe early game to last longer in the lane.

ALWAYS max his e because in lane lets say you get 1 hit off on your enemy. Early game that does about 70 damage alone early game with a dorans blade, Then when you have your e doing about 20 damage DOT which can be very devistating agnst mid mages. This allows you to harass early and win your lane. Then you max his W, This skill is the most beneficial but I think that it is not as important then W becuase you can excape very nicely.

The items i chose are very helpfull early game for there cheepness and can really dominate an enemy team. And by late can you can honsetly do so much damage with your attack speed alone. Also since teemo can farm so well that it is very easy to get those items by 30 mins in if you farm well.

I think that this is his STRONGEST point in the game, But usualy if you get a good mid game you can really start to rape face late game it kind of carries over. Early game just get your last hits, Then pump out that malady. But make sure to poke when aviliable to the enemy with your auto attack. A good tip i read from therainman teemo build was to shoot once with your auto attack, then Q then auto attack again. What this does is allow the most damage in the least time.

Just stay alive... This may seem easy but if you have a couple of items the enemy team WILL focus you down. SO stay alive and just basicly get your auto attacks in team fights but just dont over extend. Some people might rage at me for saying this but IMO i would suggest not even team fighting if it in a bad position. That may seem obvious but alot of poeple just go in willlynilly so please be carefull on teemo.

What makes a good teemo is his mushroom placement. I once read somewhere that a good teemo will almost never have 3 schrooms up. This is true beucase you can always mushroom the dragon/baron or even blue/red it is very important for that map control. Also i think a good point in teemo is to get wards. This may seem stupid because you ahve your mushrooms. But if you get like 1-2 wards here and there then you can practicly see the whole map. Just use them smart and ward like a BAUSS

I think that teemo is a very good champ, just play him smart and you can really dominate. Good luck and have fun with teemo. NEVER UNDERESTIMATE THE POWER OF THE SCOUTS CODE!!( alot of people do)
