Heart of the cards skill is legally cheating , you should not be able to dig in your deck and get a card u when the duels on the line because some people purposely take damage because of that massive advantage
My only problem with heart of cards is that it works with mausoleum.
Turn 1 javelin or apples (d shield works too), turn 2 mausoleum and joan (d draw If need/can), attack with Joan to gain more life, turn 3 d draw if need/able.
