-1 bear. Bujins can destroy monsters easily enough without him and he's counter productive to kaiser.
-1 bujingi hare. 2 should be enough when combined with turtle.
-1 tensu. It cloggys up a spell/trap card space and doesn't really help the deck much.
-1 torrential tribute. It's bad in bujins as you either nuke your own monsters or waste a hare.
-2 vanity's emptiness. You have many traps so I think you would be better siding these and maining summon limit instead.
+1 bujin mikazuchi. He has good atk and helps maintain field control should Yamato die. Also helps with making Kagutsuchi and tiger king.
+1 bujingi quilin. The ability to destroy any face-up card wheter monster, spell, or trap makes him worth running two of.
+2 summon limit. I think this will work better than vanities empitness as it's harder to remove and still let's you special summon.
+ either 2 forbidden lance or 2 dimensional prison. Lance helps your monster live while dimensional prison gets rid of monsters that can't be "destroyed".
-2 prohibiton. It clogs your spell/trap zones and you have more effective options.
+2 shadow-imprisoning mirror. good against zombies, infernities, darkworlds, gravekeepers, and blackwings.
-2 dust tornado. You already side 2 trap stun and main 3 MST, so I feel like this is overkill.
+2 closed forest. Good against madolches, gravekeepers, propcecy, and darkworlds.
-1 abyss dweller. I've never been in a situation where I needed to make him.
+1 constellar ptolmey m7. You can put itt over constellar omega and bounce cards.
-1 bujintei susanowo. You should never need to make more than two in any given game.
+1 blackship of corn. useful for getting over walls such as zenmaines.
