I'm talking about balanced as in for actual gameplay. Like if I was to (hypothetically lol) print out all these cards on card paper and get them laminated so they could pass for Konami-made cards, would their balance hold up to scrutiny as well or would their OP'dness give them away? That sort of balance.
I plan on making my OP of the thread I create to introduce them be really long lol. I'm going post images directly into the post if possible, and have a brief word about each card and its effects as well as Lore, for those who like that stuff. I don't want to give too much away but suffice to say that my archetype focuses on a game mechanic I feel is underused/under appreciated...but with a twist to make it competitive in Advanced Format against "official" decks.
Also, with regards to the card art rules, do those apply only to the art? Can I upload digital versions of real life cards just without their art and maybe replace it with something else like a blank black picture or something?
1. Yeah, then you should use Advanced (Multiples). Though a general sidenote that a lot of the reviewers can have their own degree of bias pertaining to particular designs, so...be cautious about it.
At the bare minimum, a general summary of the set as a whole will suffice (30+ words); no need to explain every single card or go into long details that'd be better suited for lab reports. And yeah, spoiler tagging might help.
2. You can upload blanks or just make a version of the artwork that won't show up on Google Images, or something that won't get lumped in as similar. Main thing is just don't use the actual card pics from the game, because that got NAS (Nihon Ad Systems; the company responsible for the anime) on Dueling Network / YGOPro's case and got them either shut down or the download removed from the site.
So yeah, either recreate the art with another program, recolor/alter it so Google Search doesn't sweep it up as similar or you can put proxy images; provided they're PG-13 in nature (I'd say PG-17 because all of YCM is at this level, but some of the DP mods have a lower tolerance level). Just don't use inappropriate pics as filler.
Granted, there are other things that DP still does that technically violate the C/D order (from what someone managed to translate from Japanese), but idea is to minimize any chances of DP being shut down. It's not perfect, but that's the general rule until something happens.
