This MMR with Ryoko is from November 2008. It's a large map.
The more I play this, the more I like it.
The surrounding corridors and antes give space for a large crowd, and thanks to platforms and teleporters being directed toward the main arena it's reasonable for dueling.
Some of the texturing isn't on par with the strength of the geometry (i.e., elevated area North of the main arena)...though, probably decent for mixing sets.
