Like it, i feel sorry for the phoenix user that gets vampirized over and over.
What i'd do if I were you is this
5v8 5v8 7t4 7t4 7t4 7t4 7t4 7t4 7t4 7t4 7t4 7t4 7t5 7t5 7t6 7t6 7t6 7t6 7t6 7t6 7t8 7t8 7ta 7tb 7tb 7te 7te 7te 7tf 7tf
Sure, it's a tad slower, but pests are safe, and 2 gargoyles can be vampirized for a 20-turn healing device.
