Not enough defense. You need to either strengthen your defense or add more site/artifact control. Four evil characters is not enough. If you want to use the sites I would sub in Pergammun for Hormah. Also, look to add in cards like King Zedekiah, Gomer, Land Purchase, Taking Naboth's Vineyard and Lying Unto God. You currently only have one way to get rid of arts, DoN, and one way to really stop sites, Land Dispute. Captured Ark and Wastelands can only be activated on your turn. If your opponent turns over an access artifact or puts a site in play from hand then you are in trouble. Philly Priests, Philly Garrison, Outpost and Crucify Him could also be helpful. I would take out the hopper lost soul. I know it can generate a soul, but alot of times it is the target of a Harvest Time or WaTW. Also, look to get the deck discard, hand discard and site guard lost souls in there. I would take out one or both of I Am Redemption and Brass Serpent. With 10 heroes you should be fine. If you are really worried about this add in chariot of fire.
