Poor Urgot

Once nasus gets one MR item, Shitmo dies.

Teemo is not a very good pick against those two. He can only hold them down for so long before they out scale him around level 6-8. Once Garen and Nasus start to beat Teemo it quickly turns into a slaughter every time the fuzzball enters lane. The blind just isn't enough to lock them down for long enough. Urgot will scale right along with both of them, can homing missile them, shred their armor, slow them, and comes with a kit that straight up says no to burst via a shield and a damage reduction. The same damage reduction being capable of messing up a Nasus' stacks as easily as a Teemo blind, but coming from an AA so there's 0 mana cost to do it over and over. You can't even farm under your turret against an Urgot with a vendetta. While Teemo is basically picked to try to keep them from getting too big for your team to handle, Urgot is picked to just kill those two over and over and over until Urgot is too big to stop.
