Quick-Play Spell Card
You can only activate a card with this card’s name once per turn.
(1) When your attacking monster destroys an opponent’s monster by battle: You can target 1 card in your GY; add it to your hand, but you cannot activate cards, or the effects of cards, with that name for the rest of this turn.
Note: As you would expect, this is a pun. The name (犬賞金, kenshoukin) sounds exactly like 懸賞金 (prize money), but with “dog” (犬) instead. He looks a little old to be a pup, though.
