Honestly I don't think he's a good ninja for anything except ranked. But if you wanna use him for 1v1, here is a moderately decent wind buff team for him
x - Konan - x
Jigokudo - Wind Main - x
x - Orochimaru x
Summon : Giant Katsuyu
Talents : 2-2-1-3-1
The idea is that it deals heavy ninjutsu damage, clones buffer, but eventually Konan or Main eats a huge combo and gets low. Orochi uses them to summon Hashirama. Jigokudo resses them back. You have a huge advantage if this plays out well.
Faster teams will eat you alive. Its generally pretty squishy.
You could also build all sorts of kabuto / Hidan / jigokudo / Sarutobi etc resurrect cheese teams. But generally speaking Orochi isnt very viable in 1v1.
