Assuming nobody bought Oracles in the last 5 minutes, they either have to A) Push and let me backdoor, or B) Hang out until I'm seen/dead. Not seeing a teemo and knowing that he's invisible somewhere on the map is a nice push deterrent. --- "How are you a vet if you can't fly and shoot laser beams?

I play a lot of ARAM so I've actually seen it happen quite a few times. I've seen Panth and TF manage to skip past a push and take it out as well as Teemo and Shaco hide in a bush and use invisibility to sneak in.
