Teemo counters udyr.. sad but true

And sivir is uncounterable one autoattack = 5 hits = 6k damage each second geegee sur 20 min.

Master yi (and well, most other AD carries) are countered by anything with a lot of armor.

Who counters orianna mid? Malzahar, Morgana, Lux (long range stuns/AoE DOTS)
Also GP is a great counter for a lot of regular solo tops. So is Garren.

Disclaimer - This is my opionion and not fact.

Boots +3 pots.
Caitlyn counters all the others ad carrys except Urgot, who counters her and all the others except Sivir and Ezreal.
Exhaust, any targeted stun, AOE spam, Bruisers, Thornmail... Pretty much everything.
Nidalee have weak harass, so capitalize that with any farm dependant solo top (Nasus, Irelia), ignore her and keep farmin'.
Everyone.
Chain Vest.
Everyone except maybe Urgot.
Caitlyn, Ezreal, any other ad with more range than him, and Bruisers with gap closer (Xin Zhao, Jax, Renekthon...), also Talon Maokai, Malz...
Anyone with range >125.
Other Bruisers.
Any ranged, Garen, Udyr, Cho Gath, Talon, Irelia.
Laning? No one.

Lee Sin counter picks everyone
