I'm not a bot but I'll be one of those that'll be greatly troubled if the free cards are phased out within a month of buying the spellbook. Besides buying the spellbook I also bought some DEC using HIVE and have plans to buy more once the price of HIVE stabilize and I'm done powering down. But even if bought my own cards, the amount of cards I could use would still be greatly limited if the plan to phase out free cards is implemented which would mean that my already terrible win rate would become even worse. I understand the concern about bots exploiting the game but I hope the devs could deal with the problem without the free cards being affected.
