This is the basic 2 warrior into full ninja combo using Flame Swordsman stuff.

You have the option to run Getsuga to search off of Hanzo after cross sheep revive and then Rahamu to summon Getsuga, revive Meizen and Hanzo, Hanzo search Mitsu and have quite a bit more bodies. Can also work in upstart golden and knightmare goblin since you'll have traps in hand to discard but that gets a lot more complicated and this end board should be enough to beat most decks.

For the OTK going second:

Just stop at Isolde + Meizen. Equip Isolde with Digger and Gearblade, attack direct, trigger gearblade, attack direct x2 with both. GG!

Playing your turn 2, you can use flame sword dance to summon OG flame swordsman to flip a card f/d and then after you use salamandra with chain, you can use it's GY effect to make ultimate flame swordsman, equipping fighting flame dragon fusion from GY to UFS to make his pop a quick effect!
