So I just played a match against the "Wrath AI".
I was using "Earthbind" from LEA on a "Skyhunter Skirmisher" and was actually expecting it to kill the skirmisher since it's a 1/1 flying creature and Earthbind is supposed to deal 2 damage to it. Unfortunately it didn't take any damage and also didn't lose its flying ability either, which was supposed to be the second effect of "Earthbind". (When it attacked the next round, I was unable to block it with my non flying creatures)

I'm using the 0.16.0 version of the game in a Windows XP SP2 environment.
