Play Six Samurai united, Summon a regular six samurai card+grandmaster's effect (gets special summoned)+ Shogun Shien's effect (gets special summoned). Then use united and draw 2 cards.

lol

To add to that combo o wait he basically said the entire point of the 6 samurai deck to get out Shien but yea here is another combo

When someone destroys another Samurai (ex: Irou, Zanji, etc) and u have Grandmaster on field use their effect to transfer to Grandmaster so u can spam his effect and bring back to hand
*correct me if i am wrong

Old post, but wrong. If your opponent activates an effect to destroy one of your "Six Samurai" monsters and you use the effect of the "Six Samurai" monster to destroy your "Grandmaster of the Six Samurai", "Grandmaster of the Six Samurai's" effect doesn't activate because it was destroyed by your "Six Samurai" monster and not by your opponent's card effect.

Other Combos:
Book of Moon + The Six Samurai - Irou
The Six Samurai - Zanji + Mist Body

heres another on summon 1 six samurai monster put down double summon summon another six samurai then grandmaster then shien.

use double edged blade teqhnique to bring back 2 six samura and use hand of the six samurai to destroy thoughs 2 monsters and 2 cards on the field so you dont take dmg and you can destroy 2 cards on your opnents field
