For summoner spells get heal and flash for vayne's tiny health pool and for getting out of teamfights and in. Vayne has alot of damage output but she is not a good early game carry, her range is very small. For example me as Vayne vs Caitlyn and Ashe in lane and they crushed me. So instead if you have trouble with some ad carrries ask someone to switch lanes with you beacause you because you dont want to be dead alot. You want to be fed. Fed Vayne = Pentakill ( I went 20-4-3 and got a penta so dont fed them or some bad stuff will happen and if you want to switch your black clever with another phantom dancer.
