Choose an opponent. At the beginning of their end step, if no damage was dealt to you this turn then put 1 fire counter on Hellbringer. If you were attacked during their end step, remove 1 fire counter from Hellbringer. If there are 10 or more fire counters on Hellbringer, you get an emblem called Hell with "You cannot loose the game and your opponents cannot win the game. At the beginning of each upkeep, deal 2 damage to all opponents."
