- If Gemini Elf attacks a Defense Position Battle Footballer, and Gemini Elf's controller takes 200 damage, then Begone, Knave!'s effect will send Battle Footballer back to its owner's hand.
- The effect of Begone, Knave! can be on a chain.
- The effect of Begone, Knave! is applied to the monster that inflicts Battle Damage to the player, so if Amazoness Swords Woman battles a stronger monster, Amazoness Swords Woman would normally be returned to the owner's hand, but because she is destroyed and sent to the GY, she will not be returned.
