If I contradict anything I said in the past, it means Ive scratched the idea and its not good.
As I said on DN, -1 Kageki and +1 Kizan. Kizan doesn't drain a Normal Summon, with 3 you can pull off broken combos with Gateway, and he makes Barkion.
Next, since this is a Dojo build, I suggest -1 Yaichi and +1 Spirit. Spirit can cause major pluses with Shi En and turns him into an unstoppable 3k powerhouse.
-1 Double Edged Sword Technique, good card but should be at 1 to make more room. +1 Asceticism cause its freakin amazing
-1 Book of Moon and -1 Mind Control, cause no matter how good they are in other decks, they just cramp things up in Six Sams. Also we neec to make more damn room!!!! Instead, +2 Compulsory Evacuation Device, its probably one of the best traps in the game.
Finally -2 Forbidden Lance to make room for 2 Bottomless Trap Hole.
More detailed fixes later.
