Get items quick. Head to bot lane brush (the one closer to bot lane enemy turret). Wait for enemy champion to get in range of boomerang (you can ambush if you have a stun support like Lux, she has good range with stun too), and as soon as one does hit them with it. Claim that bush (mark your territory!), and keep zoning/poking enemy champion with boomerang if possible. Stay in their bush if possible until minions come, then set ward in bush and fall back if you so choose to aim for minions. Drink potion (buy more if you need it) for more mana, and more mana means more poking with boomerang and more minion kills, so it pays itself off in a sense. Cast clarity for you and your support. Sustain lane for as long as possible before recalling, and set up as many ambushes as you can with your support (Lux or Zilean would be preferred). Screw health potions because if you are taking damage from the enemy champion with your zoning/poking capabilities and barrier to feed on their mana, then you have already failed. Oh ya, and did I mention that you are supposed to feed on their mana with your barrier? Time sh*t that to the max. Walk over Teemo mushrooms like a BOSS. Ad carry lane as much as possible if turret low on health please aim for turret (with support) not champion. If turret full, then throw boomerang and fall back before turret can aim for you. And finally, do Ash or Lux aim at you with their ults? No they aim at you with free mana, your mana! And Psssshh screw, Nidalee and Caitlyn with their traps walk over them like a mana stealing BOSS.
