What is a good team set-up for me to use for the Rashomon event?

You have an orion and andersen, which means you can put together one of the most powerful team comps in the game - arts meme stall. The original team consists of Tamamo, Waver, and Orion, but Andersen does a decent job of replacing Waver. Borrow a freinds Tamamo and stall like crazy, Pop off Tamamo and Hans Np as much as possible, and use Orions and Tamamo's stall skills as soon as they come off cooldown. The team comp is heavily reliant on stalling and arts Np spamming, so buff Orion's NP with Tamamo's Fox wedding as often as you can.
