So volatility is back to the reward cards market and therefore you can make lots of money by buying most used cards and then selling them for profit but it's not a financial and trading is risky. Almost every card prices went up and only few unaffected against the bull market and some reward card prices went up even 300-400%. For example 1 or two months ago after season end Brownie was trading at 20 cents and now it's almost one usd which is 450-500% increase. I myself like brownie because this card helps the team a lot with giving 1+ speed and melee attack to all friendly momsters.
