I just tried it in ranked.
It seems like might make sense.
1. Teemo has increased movespeed to dodge his grabs
2. If he or the ad get grabbed he blinds rhe ad for almost no dmg
3. When blitz misses the grab he can poke like a boss
4. Can eliminate blitz chases via shrooms
Idk seemed to work well. Was considering going alistar insteqd but trying to learn teemo
