Answer: (Don't read if you don't want to be spoiled) Troll

Trust me I tested it. It was a close battle but in the end this outcome happened.

Which troll did you test with, the log troll or the no-log-on-hand troll? asking just coz I'm curious and I don't wanna experiment on this :P

Put em against each other, the troll barely lost, and it was a blue troll. For the green and red ones it would be an easy win for the trolls.
