Quest for Pure Flame

Whenever a source you control deals damage to an opponent, you may put a quest counter on this enchantment. Remove four quest counters from this enchantment and sacrifice it: If any source you control would deal damage to a permanent or player this turn, it deals double that damage to that permanent or player instead.
