Link summon Isolde and use ninja cards like Hanzo and Jogen to generate advantage, then annoy your opponent with ninjitsu art cards. Not a particularly strong deck, but a fun one nonetheless.
Fire Flint Lady (searchable with Durendal) and Jogen are both extenders, allowing you to normal summon any warrior type ninja and link into Isolde. Upstart Golden Ninja is a good but vulnerable starter, and it not being once per turn allows you to spam Hanzo and copies of itself from the deck with its own effect to spam monsters for XYZ/link plays, provided there are enough traps in your hand.
Isolde allows you to search Kagen with her first effect, letting you pendulum summon Twilight Ninja Getsuga to summon copies of Hanzo from the GY. Hanzo's ridiculous ability not being once per turn makes it possible to search every ninja card in the deck in one turn if your hand is decent.
Ninja Grandmaster Saizo allows you to set any ninjitsu art card from the deck, which can be used to draw cards via notebook into alchemy, set up a disruption or floodgate with the transformation cards into Amorphage Greed/Barrier Statue of the Stormwinds, or just set the field spell and activate it to provide protection and recursion for the ninjas and ninjutsu arts.
The abundance of search effects makes it possible to bait handtraps from your opponent (although the deck is especially vulnerable at the beginning and dies hard to droll), and allows you to generate insane hand and field advantage, allowing you to link summon Saryuja with four monsters and extend into even more plays, as well as maintaining hand advantage.
The side deck includes other options to shut down other types of decks, with Anti-Spell Fragrance and Dark Simorgh in conjunction with each other allowing you to prevent your opponent from using spells and traps. It also contains a few going second cards, since this deck struggles in that department.
Overall a fun and somewhat quirky deck which is sure to surprise any unprepared opponent.
