This is an interesting thread.
In principle, the question of whether variations are TCDB-worthy variations depends on if the manufacturer intended to create those variations. That's the gospel, right?
But unless the manufacturer made it clear that they intentionally made those variations, we will never know their intentions. So, sometimes it's guesswork. This set is a good example. Leaf never announced a gold-foil parallel, so according to gospel, it's just a print variation and not worthy of being listed. I'm OK with that.
But this particular variation is fairly well known, and seems to apply to all cards in the set. And most importantly, Admin says it shall be listed. I'm OK with that too.
If that sounds wishy-washy, that's because it is. There's no black-and-white line to be drawn here. For any rule anyone makes, someone can easily present a gray-area example that isn't totally settled by that rule.
Here's my opinion, for what it's worth. As an obscure variation hunter, I think this stuff is fun. I'd rather see TCDB err on the side of including more variations than fewer.
