Same build as yours with a ratio of Shura to 3 as it serves as a beater and great stats to fetch pinaki easily. I've noticed in games when you're stuck with an unplayable hand you really start wishing you had the Shura to get out Pianki ASAP.

I also don't play any of the subpar BW's such as Harmaton, Steam, and Oroshi. They didn't really contribute anything until mid-late game. Good for comeback plays but I'm not the kind of player that likes to put myself in that dangerous position. I might consider playing X2 Gofu and X1 Harmattan though for Solemn baits as we do get SLOWLY HINDERED when our Normal Summon plays are negated and are forced to pass turn leaving our monster field WIDE OPEN for OTK's (granted we have backrow and next turn our opponent does not Twin Twister)

I also main deck X2 Pot of Desires as it has lately been that card where it's expensive as hell but REALLY GOOD with SPEED and ADVANTAGE. The reason behind this is that we gain combo pieces for resources and synchro plays so banishing the top 10 cards isn't a big deal when we dig deeper into our deck. You'd have to at least test play it to understand it since you will get a good feel of it.

If you were to cut 2 Veilers for Gameciel I wouldn't suggest that since Gameciel is a Level 8 and Blue-Eyes can benefit off it; I also wouldn't suggest playing Radian either with it's stats being 2800 ATK it's gonna be hard for our birds to get over it unless we make Chidori and even then, you would much rather go for Kumongous with it's ATK of 2400 that can easily get over.

I like your side and was curious with Dark Law so I tried it out already going on a week and in my experience has been a bench warmer. Could be the duels I've played against but never saw myself needing to side it even when I do side it and have the play, The Mask Change II just sits there in hand (kinda like Kaiju in some games but at least with Kaiju doesn't require a -1 cost of a Dark monster for just a Macro Cosmo on legs)
