- Coffin Seller applies its effect when monster(s) are sent from the hand, Deck, or the field to the GY.
- If multiple monsters are sent to the GY at the same time (due to Dark Hole, etc.) then inflict 300 damage only because it is considered as 1 time.
- Multiple copies of Coffin Seller are cumulative.
