I've also found that backflips are great on Levi. When Levi goes for the flop, be sure to stand on the water spout side, this will be where his head spawns. As you're sliding down on the flop towards Levi's head, hit him with a phlebotomize, square up to the head, then backflip to the tail which should be coming up just as you land (tail comes up a few seconds after the head). Just be careful not to flip off the edge
