This is by far the best orochimaru. Him + end of the demon = your opponent's ninja dying like crazy. I use him to get my kabuto: stock out after i end of the demon the zabuza i got earlier from haku dying. then, if i need to, on a later turn i'll end of the demon my kabuto and use the mission and hand cost as the chakra cost to put kabuto back in play. also a great way to deal with some of the new ridiculous clients. and mastery on him to boot!
