Shaco is rather easy to controll with mage such as malzahar, or ADC with decent range (cait is superb). But if ARURF RNG will screw you with something melee with little poke, just swap lanes. If you won't swap, at very best you'll keep your lane with shaco from falling while he'll get enough gold to steamroll, at worst he'll be competent enough to poke and harrass you pushing you away, then taking the turret then flooding other lanes with his ganks.
Also very important is getting oracle lens. Those are required to deal with Shaco/teemo.
Other than that just pray to RNG not to give you something worthless
