That all sounds wonderful! Besides what you mentioned, the biggest thing I'd love to see implemented into the plugin is a way to control the cost dynamically. Discounting card costs is a common mechanic in card games, and although I tried to implement this in Alyx Ascended, it was done so clumsily since I couldn't show the new cost of the card. It would be a great debuff to players as well, if an enemy could increase card costs, or randomize them, etc.- there's a lot of possibilities with it :)
