Nice concept but very buggy. Taint won't damage sometimes, creatures often won't attack, when creatures do attack sometimes they do no damage for no reason (i.e. 6 damage, 2 defense = 0 damage),
Megalomania helps the enemy far too much, no ability to customize deck (do we really need 4 blackmails?), blackmail gives opponent extra turn when they play it..
