In a fight at bottom, i would Ambush to get behind them without the seeing me do it. Get my support to start a fight and kill them from behind in early game. In team fight i will pop my ult and get them all poisoned, then use my Expunge to kill them or bring them down in health. early game try to dodge tank's also late game try not to get the tanks on you. If they do attack try to go invisible and wait till they run then attempt again to kill them. It is best to lane with a Soraka because of her heal and mana regen.
