Hearthstone Tavern in Marvel

Ike Brandi, who traveled to the Marvel world with a magically modified version of the "Hearthstone System", began his own story... Start with a "Hearthstone Tavern", and its development depends on krypton gold. Xuan will not save Fei, but Krypton will not change his fate! ... Who can tell me why I don't have a "mana crystal"! Looking at the piles of "cards" in front of me, can anyone tell me what to do? ————————————— Welcome to my pub I'm very tired tonight, but I welcome guests (rich people) to come and play. ————————————— PS: If you haven't played Hearthstone, it won't affect your viewing.
