/1/ Because they want to sell the promo cards for the same price they charged for Zyriel, but hardly anyone bought that cos it was a ripoff. So they've done some hocus pocus to make it seem like they're selling the cards for $31 while ensuring they get as much profit as if they sold them for double that price, but getting the funds from the DAO instead lol.

/4/ Yes. The game is a massive ripoff owing to the team's frankly idiotic position on multi accounting bots, meaning the value of ordinary players assets suffers a near constant drain, and it deserves to fail thanks to the way it keeps gut-punching existing human players, making changes to ensure the value of old cards gets destroyed because they want existing players to keep being suckers buying new sets. Bought loads of Alpha, Beta or Untamed cards to play wild in the past? F U! You're getting nothing but merits potions and soulbound cards! Naturally the same will happen to CL and Rebellion too in a year or two too!
