As I play the game more I'm noticing a lot of bugs, but I definitely want to help you expand this mod. I'm absolutely loving it! I've played it more on android than default Wagic.
Some more things I've noticed:
1) Defender doesn't work. Walls can still attack which makes them a little unbalanced.
2) Arthur's bonus to knights affects your opponent's and vice versa so that if you are playing Arthur vs Arthur all knights on the field get +20/+20. I haven't tested this for the dragon bonuses but I would think its the same. I don't like the orcs as much as the humans but I'll play them until I can confirm they have the same glitch.
Also, here's the link to my first set of completely open source card images. Let me know what you think and if you think they look good I can start on the Orc set. I'd like to help develop some new cards too. It'd be nice if there were more than four spells. A few racial spells and some general spells too.http://www.megaupload.com/?d=PE8L4ODJ
