A new form of evil...
All other Teemo players build AP(for shroom damage) and on hit(applies damage and effects when you attack) items for their shrooms and basic attacks. I build a form of evil like no other. One just meant to burst and kill and aggravate a single person. And then to split push with the Zz'rot portal so that I can draw in more sacrifices to my altar, who desperately tries to stop the pushing. Meanwhile my team is capturing Baron, Dragon, other lanes and winning on behalf of my evil lordship.
Suggested build: Varies against lanes Doran's Ring or Corrupting potion. Hextech Revolver or Bilgewater Cutlass. Sorc Treads. Either buy your Haunting Guise if they have heavy pen or complete gunblade otherwise. Build Liandry's. Zz'rot. Lichbane for more dueling power. Rabadon's if the enemies last that long without rage quitting.
So go forth my minions, go forth and do the evil!
On a serious note. I play Teemo when their top lane counters or bans Riven and Shyvana. And I am not yet confident in my Quinn skills to use her as a counterpick. This build works if the rest of your team is competent, otherwise they will need you in fights and objectives. If your team is competent, your goal is to focus on ownership of one corner of their jungle, while you split push top. If you feel overwhelmed by them sending too many after you and clearing shrooms. You can rejoin your team or switch to pushing bot. Otherwise your team can capitalize on your Proxy Singed levels of aggro and get objectives. And unlike Proxy Singed this build isn't about feeding or completely ignoring your team's needs. It's a pressure build. If things go south you can trade one of your items for a Nashor's to give you DPS. But this build is about burst, kiting and pushing.
Try it, and be evil :3
