Suggested by Anonymous While Yami does have the edge in monsters here, I don’t think he will be able to stop Roshi. Roshi has Ultra Instinct now and that will complement his speed to a dangerous level. Yami will have a tough time keeping up with him and even his monsters won’t be able to protect the duelist for long. The Kamehameha waves will leave too much of an impact. Master Roshi wins.
