Oh wow, forgot this was still a thing for second there.

[@Ammokkx] Since you asked for it, I suppose I should enlighten you on what I was thinking for deck choices.

I originally wanted Jurracs for Kirari, figuring they'd best represent her competitive spirit due to the battle interactions that they're known for. Unfortunately I got sniped out of them to an extent (can't exactly have 2 Jurrac users running around), so I made alterations to the deck so that Lost World would be the primary focus of it. I was hoping Lost World shenanigans would play on her stubbornness and her desire to stand up to those that would look down on her, and sometimes you have to fight high ATK beatsticks with high ATK beatsticks.

With Juzaburo, I was trying to sell him off as the "grizzled veteran" type of guy; as such, I looked into how Kaiba was made as a character as I was trying to bring life into him, figuring Kaiba's character would make for a good basis. (I guess you can add Kaiba knock-off to my Scooby Gang of lesbian, extra thicc girl and cross-dresser with existential crisis now that I've said that, but eh; that's what I get for writing them in in the first place.) I originally had a vanilla beatdown deck in mind for Juzaburo to use, but since Kaiba was such a heavy inspiration on his design, I thought I'd might as well go the full nine yards and just give Juzaburo a Blue-Eyes deck. After all, the lower-statted support mons kinda symbolize his softer side to an extent. I'm surprised you haven't picked up on the link based on the blue eyes and the white hair alone, though I guess you don't take appearances into account... which I guess makes sense.

You [i]do[/i] get points for seeing what I was trying to do for Yakumo... if only a little. Lockdown decks in general would've fit his style of play just fine; it was just a matter of finding one that seemed fairly generic. Hence SkillDrain.dek.

As for Wazuka, I could've probably developed her a bit more now that I think about it, but hindsight's 20/20. In any case, for her, I wanted an archtype whose mons were all cute and primarily female, since that would (hopefully) aid in the presentation of her facade of innocence... and Madolches were, high-key, the only archtype I could think of at the time. I realize this may scream afterthought, and there might be decks that probably suit her better, but I stand by my decision of giving Wazuka Madolches.

Finally, idea of giving Long Scraps was that they'd represent his humble beginnings of having to start his Harmonia journey from scratch, building his skills up from what would essentially be nothing. Junks could've worked just as well in regards to that symbolism now that I think about it. But I was primarily looking for a deck that'd be easy to learn and that would, theoretically at least, stand up to all the top decks that the world of Yugioh would have to offer if played well enough.

And there you have it; some insight on why I chose what I did for each char.
