Hey, you might think this isn't true, but the first thing to defeat me was the War Oni. I was soloing the dungeon, i got to the War Oni and I had no prisms in my deck and I am fire, so I died, and i called some of my friends over to help (I didn't have ta start all over cuz if ya leave for less than 30 min. you can resume the dungeon). On my other Ice Wizard, now he is lvl 10, but when using him, i thought i had frost beetle in my deck, so i deleted all my "minor ice shard" cards which are 45 damage no pips but i got rid of all of them i noticed i had no cards, so that meant i did not have frost beetle in my deck, so i just passed and waited to die.
