Rulings
- You can only activate Big Burn when an EFFECT that removes monsters in the GY is activated. So you can't activate Big Burn when a player removes monsters in the GY as a COST to Special Summon Black Luster Soldier - Envoy of the Beginning, Chaos Emperor Dragon - Envoy of the End, or to activate the effect of Strike Ninja or Freed the Brave Wanderer. Nor can you use Big Burn when monsters are removed for a condition.
- Big Burn's effect is negated if Necrovalley is active.
- You can chain Big Burn to effects like Disappear, The Shallow Grave, or Spear Cretin.
- You can't activate Big Burn when Sinister Serpent activates in the GY, because Sinister Serpent doesn't target.
- When Spirit Elimination is activated and Big Burn is chained, the player who activated Spirit Elimination removes all monsters on his side of the field. The other player removes all monsters in the GY as usual.
