Question time!
Master Hunter: Enemy loses recruits and takes damage based on discarded card cost. What are the specifics of this? If Crimson hawk (cost:8r) is discarded, does the opponent take 8 damage and lose 8 recruits? 4 of each? 8 recruits unless the opponent doesn't have that many, so the overage is dealt as damage? What if Chimera (cost:30g20r) is discarded? Does it have an effect based on the full 50 resource cost, or does it only refer to the 20r? Would it reduce recruits by more than 20 since the full cost is higher? It's hard to tell right now exactly what this card is going to do.
Javeliner: If your opponent has 4 or less tower, this will put it to 0 and end the battle. Is this intended, or will it have a limitation added to it before going live?
