Chaos Witch Quelaag

Whenever Quelaag deals damage to a creature, this creature gets a burning counter. A burning counter deals 1 damage to the creature at the beginning of each players upkeep.
When Quelaag enters the battlefield, create 3 enchantment tokens named Lava Pit with "Whenever a creature an enemy controls attacks, you may sacrifice this enchantment.
If you do, deal 2 damage to the attacking creature."
