With the arrival of the new patch, they changed Cursed Catacombs from " Discover a minion from your deck" to “Discover a card from your deck”. Now all of a sudden combos like Dorian + C.Catacombs does not work, you cannot find Agamaggan in any way and the whole deck is now broken down. I just crafted the deck and used 16k mana dust. Thanks Blizzard
