Alright well I seem to have run into quite a few bugs simultaneously.
playing against good ol' gregg.mott and had him beat, we each had a single card in our hands; he was at 16 and I was at 56 or something; me with two crimson dragons on the field and he with nothing except pillars. Then on his turn he drew six cards, popped out a black dragon, shard of regeneration and weapon (the vampire thing) and ended the turn. When he ended he jumped from 16 to 100 health and then continued drawing cards to fill his hand, playing dragons and regenerating up to 100 each turn.
Not sure what might have beset this; but I'd suggest it's looked into. (I feel stupid for not taking a screen shot, then again thw screen shot would've been after the regen and I wouldn't be able to provide anyhting anyway)
