Silva is a pretty powerful member of the Shaman fight. He certainly gave Yoh a good fight and I was glad about this because up to now most of the organizers weren’t too impressive. That said, Yoh certainly surpassed him by a wide margin. Silva’s totem attacks are too limited compared to the many ways in which Yoh can manifest his OS. He would definitely be able to outmaneuver Silva consistently and shatter any defense that the guy has. Yoh wins.
