I thought I was being clever when I made a deck intent on injuring myself with spells while having Jade Shield equipped. My plan was to make my element mark Darkness and then use six Holy Lights on myself. The card Holy Light's description says "Heal the target for up to 10 HP’s. If the target’s element is death or darkness, damage is dealt instead." In the test run of my deck, the Holy Lights healed me instead of dealing ten damage to the enemy when I had mark of Darkness and Jade Shield on. My plan was foiled. I don't know if the Jade Shield had any effect in this, or if the Holy Light's just don't deal ten damage to yourself when you have the mark. Either way, I think that using Holy Light on yourself with the mark of Death or Darkness should deal damage, and with a reflective shield, deal the damage to the opponent.

EDIT: I do not know why there is a 31st card in the deck generator. There is not supposed to be a 31st card in the deck.
