Teemo is the favorite champion of many. His speed, cunning and the combination of attackspeed and toxic shot is perfect to earn his title: Swift scout. But.... for that you also need the perfect build, and I claim to have found it! ;)

Items:
-Health Relic
-Boots of Speed
-Zeal
-Phage (upgrade of health relic)
-Berserker's Greaves (upgrade of Boots of Speed)
-Phantom Dancer (upgrade of Zeal)
-Frozen Mallet (upgrade of Phage)
-Infinity Eadge (might take awile to buy, if youre not earning enough money, buy a Last Whisper)
-Ionic Spark
-Blood Thirster

The result: a heavy damage Teemo with enough healh to survive a gank!
Have fun ;D
