Suggested by Sonic Kirisame is a skilled sword user who basically stopped appearing since the 2nd season but shows up once in a while to have some fun. This has hurt him in regards to getting new cards but the ones that he already has are pretty good. I doubt any are a match for Cerberus but how about if they all team up in him? Cerberus is strong but I think at that point they would be able to overpower him. Especially since Kirisama will be in there as support with his own skills and magic shields. Shosetsu Kirisama wins.
