Do you think we'll see Conspiracies (the card type) again? They're one of my favorite things in my cube.

I think there’s a chance. It might not necessarily be tied to multiplayer play though.

If Conspiracies were acorn/silver border, wouldn't that make it so that they would not be legal in strictly non-acorn cubes?

Cubes have no inherent legality. Designers can include whatever cards they wish.

"That’s basically silver borders/acorn which is what Conspiracies should have been."Isn't a big distinction between silver border/acorn and regular black border, their interaction with the rules?You can throw in a pack of Conspiracy in any draft (Chaos or regular) and all rulings involving the draft-matter cards will 100% comply with the rules of the game. A lot of them can even be played in eternal format. Since you didn't draft them, some of their effects don't do a thing, but they still work. (It wasn't drafted, so no cards were revealed this way for instance).

Conspiracies had to be banned from constructed formats. There’s no reason to do that when we have technology that does it without having to gum up a banned list.

Conspiracies aside, do you think more "draft matters" mechanics are an if or a when?

They’re an if, but I’d like them to be a when. I think they’re more likely to show up in a product aimed at two-player play than multiplayer, as the biggest fans of draft tend to prefer two-player games.

In the same way bonus sheets are legal in limited but not standard, could we see something similar with conspiracies in a non-conspiracy set?

Conspiracies are core to any set that’s using them. I do think we might use something like acorn technology if we do them again, so we don’t have to list them all on a ban list.

"I believe Conspiracies would have been acorn if that technology existed at the time" can we get more since they are black border? Conspiracy was a really fun set, so was Battlebond for that matter. A lot of us want more of those specifically.

Whether or not we mark the conspiracies as acorn or just list them as banned/make them unlegal in every constructed format doesn’t affect whether or not we’ll make more.

RE: Conspiracies being black border - Does the acorn stamp technology increase the liklihood of one-off acorn cards/mechanics in otherwise fully black border supplemental sets (for drafting, etc.)?

Time will tell.

I heard that New Capenna is coming out with not only the first standard-legal Conspiracies, but also Conspiracy Creatures, is this true??

Absolutely. All the Leprechauns are Conspiracy creatures, half are compleated.

Regarding Spike, Tournament Grinder and conspiracy cards: wouldn't the last part of rule 314.3 [Conspiracy cards that aren't in the game can't be brought into the game] prevent Spike from bringing a conspiracy card into the game in the first place? Or does silver-bordered land not care about such paltry restrictions?

No, silver border does care about things like that, so I guess Spike can’t get Conspiracies.

"Conspiracies should have had a new frame color." I've argued with some that Conspiracies should have been silver bordered. Can you explain why a new color would be better for them than silver?

Silver border has connotations beyond “can’t be played in tournaments”.
