Yet another match ended with opponent able to cast more spells than they had available mana for. It is beginning to look like some group of players have developed a HACK FOR ARENA... It doesn't seem probable that these errors are connected to individual cards anymore... i mean how hard is it to program a simple step like: cast spell requires x mana : sufficient mana avail? : y/n
I don't think your programming is that bad. More likely you guys need to secure the app from whatever manipulation is being done
