This is the best team I could find for farming Kanetsugu. I may go into possible substitutions or other teams later, but for now I wanted to get this video out before too much time passed.
4F: Uzume if bound → Kagutsuchi → TPA
6F: Kenshin (water): Shiva Dragon → Goemon nuke; Masamune (wood): Set → do some matching
7F: Shiva Dragon if you need it → swipe Goemon
Uzume can be skill level 1. Kagutsuchi should be at least skill level 2. Although all skill levels can be flexible depending on how you use your Shiva Dragon hastes.
The amount of combos you need to do depends on how many +eggs the team has, Shiva Dragon and Set in particular. Most teams can probably use sub-element TPAs to clear floor 2.
