I as well agree with celes, tbh I think the only reason bujincarnation is even ran in bujinns is cuz mikazuchi searches it. Personally I wouldn't run it at all if it weren't for that. It's a very cloggy card, and requires you to be at a disadvantage to use. you really only need one (if any). the only justifiable reason to run 3 is if you run summoner monk for when it is dead. Let me also stress how important it is to run either kaiser colloseum OR black garden. those cards are literally bujinns win conditions. kaiser colloseum lets you sit on a yamato forever, and completely prevents them from xyz summoning, or synchro summoning as long as you control only 1 monster. With kaiser colloseum you can literally just beat your opponent to death with yamato. Black garden however, is a much more offensive approach (as in otk offensive) you play double summon summon 2 bujins xyz for susanowo. thats it. thats game. garden would have summoned 3 tokens to your opponents side of the field now you just use susanowos effect to search for a crane, double his attack and attack every single token. If you do not run either kaiser or black garden, your win condition really isnt there other than beating over their monsters with susanowo.
