I had this idea. The idea of the most obnoxious bujin deck ever.
You know how hard it is to get rid of Yamato with all the bujin relic support (I'll call habakiri & co this way :< ). I wanted to make it even harder.
So I teched three cards (three of a kind). A most awesome card, especially in bujins. But in five games in a row I couldn't draw it. I think I won 4, maybe only three. But the point is I didn't draw my awesome tech, which would have make my deck more unique, you know, more personnal (not only that, but it would have prevented the time I got otk'd :< ).
So I decided in a sixth game, to not finish my opponent until I draw it, and bujin being quite plus, and even more now with arasuda, I was like, it won't take long, and if I lose in the mean time oh well (I will get mad O_O).
In the end, I got the upper hand during the whole game. I could have finished him a bajilion time and in a thousand bajilion ways different, but as stated above, I decided to wait and draw my tech. I run three of it. The probability to draw it first turn is actually technically approximately 50%. I was like odds weren't in my favor for 5 games now, now tis time for me to get this 50% chance (and not freakin 0% dang it !).
Gladfully bujins have a pretty good defensive stand (right Luna

?). So good defensive stand, that in the end I had to let my monsters die, because if I saved them, I would have had to use habakiri/yata, and it would have made my opponent lose ! Ugh...
Yes, I did got into a point where I went through such a huge amount of cards, and the game had lasted already for so long that we got to a point where I would kill my opponent if I protect myself. But I did let him kill my monsters.
And finally I drew it. It was my 35th card... I play three of it. All of which were among the freakin last 6 cards ! My luck I swear O_O
I didn't want to end it on only drawing it, so I made the duel last three (three again for who reads me O_O) more turns, and this tech did reveal itself to be pretty amazing ^^
In the end though, I have been pretty impress : Bujins are so good, I could basically decide to do whatever I wanted to do and not die doing so. I even won in the end. It did impress me, how good defensively bujins are :O
But this damn game sometimes I swear :/

https://i.imgur.com/k5rzUye.pngYup, the tech is summon breaker. If you summon three times, your turn ends. Basically if you summon one monster. then a second one. Then either synchro or xyz with it, your turn end right away. ANY (almost) xyz/synchro play means the end of your turn (of both players, but that's the point : bujins barely summon more than twice per turn). You want to go scrap and waste one of my hetsuka ? Well, too bad, your turn ends before you get to use its effect. You want to go Pleaides and do the same ? Well too bad your turn ends. (well, Pleiades does have a quick-effect though :PI just wanted to mention lryu's deck

). You want to go ham, summon triple Gadjiltron dragon, go heliopolis, nuke my whole field (heliopolis doesn't target, which is awesome against yamato). WELL FREAKIN TOO BAD ! End phase already :PWell Luna does play geartown, but she has to draw it, and then I have to have neither mst or anything to "negate" the activation and keep summon breaker :]
But yeah, you can only summon two monsters and do some shenannigans, becasue once you get your third summon, you can't even use spells, your turn just ends

And now, first turn hetsuka in grave and habakiri in hand is pretty consistent. (technically, as long as you have yamato it is technically almost 100% Then again, as proved above, maths can't predict everything...). And that not counting eventual fiendish chains, lance... With only two summons, you have to get rid of yamato... Trust me, it ain't easy. And that lets me all the time I wish for to set up

Few decks are consistent without summoning at least three times in one turn. Actually only (and I mean it, ONLY) stun decks, bujins and spellbook (becasue any xyz play; besides for instance the bujin spell cards -told you bujin can play really well with summon breaker on field

- or the heraldic one, most xyz play requires at least three summons : the two materials and the xyz. And same thing for synchros. And try getting over Yamato without that. I mean even with that it is hard. BLS can't do crap to Yamato. banish it ? hetsuka. Kill it ? Habakiri.). And not all stun decks are good. Summon breaker is the most effective against dragunities

BUT for the moment, I didn't really got to use it :/
At least, here is my thought process I guess. And try it out, it must (you can't even imagine how much I want to say it is, but since, I couldn't relly test it yet...) be much fun ^^
And at the very least, they will mst summon breaker, which makes all your traps live. Or as I imagine it in my head, once they mst the field spell, activate vanity's emptiness ^^ They would cry lol. But yeah, it is a good bait, and a waste of backrow popping stuff, and when it dies, bam vanity. Or once they get rid of vanity, they have one turn, and then, bam summon breaker. Vanity being a trap, it is better to activate summon breaker first, if you draw it that is...
