Nourii-chan's a very bad Samurai!

It only needs 1-2 Musakani (Depends on how scared you are ;P)
Also, Double edged isnt really used that much anymore so either 0-1 it.

if it was my deck I would
-2 Musakani
-2 Double Edged
-1 Great Shogun Shien

+2 Grandmasters.
+1 Kageki
+2 Upstart Goblin

It's no longer an easy win deck at all. Konami hating on Synchros doesn't do good for this deck.

Now on topic:

-1 great shogun (useless).
-1 Elder
-3 Magatama (the hell? maybe 1, ok, but 3???)

+1 LSS Enishi (I love this guy, makes Asceticism better)
+1 Zanji (same).
+1 Asceticism
+2 CED

-1 Barkion
-1 Stardust (meh...nuff said)

+1 Heroic Champion Excalibur
+1 Blade Armor Ninja

Would try to find some space for Roach as well.

Btw, I thought I would see random stuff like Shien's Daredevil but it looks competitive...You're getting it, congrats.
