Korean Yugioh PP16-KR005 “Flint Cragger” Secret

If this card is Special Summoned: You can discard 1 card, and if you do, send 1 “Fossil” Fusion Monster from your Extra Deck to the GY. If this card is sent from the field to the GY: You can inflict 500 damage to your opponent, then, if “Fossil Fusion” is in your GY, you can return 1 of your banished “Fossil Fusion”, or 1 card that specifically lists that card in its text, to the GY. You can only use each effect of “Flint Cragger” once per turn.
