Yes, things don't look great from the economic standpoint and that might affect the end of the bull market.
I don't know what to say about Conclave Arcana. The set itself is enticing, I've heard a couple of major whales getting exciting and ready for it, but you are right, not many are doing well these days. I also heard "predictions" that the presale will be sold out in less than a day, that's how confident some are or how high the hype is... The fact is we don't even know the details yet.
Presale being sold out fast is easy to expect. That is when the existing Whales go all in on Conclave Arcana. The real question is how long the momentum would last.
Rebellion didn't sold out easy in the presale. But it's a different situation now.
