The "On The Brink" challenge is way too unfair... The enemy has too many unblockable creatures, so the only way to save myself is to be lucky enough to start with a bangage and hope he doesn't attack on the first turn. SUCKS!!!
There appears to be a bug with the Unholy Power Book Badge. I dealt 27 damage in a single attack and didn't get the badge.
There also appears to be a bug with the Cruising to Craziness Badge. Ive finished several rounds while going insane and havn't gotten the badge.
