Berserker Soul (DRLG-EN007) - Secret Rare

When a monster you control inflicts 1500 or less damage to your opponent by a direct attack: Discard your entire hand (min.1); excavate the top card of your Deck, and if it is a Monster Card, send it to the Graveyard, and if you do that, inflict 500 damage to your opponent, then repeat this effect up to 7 more times or until you excavate a non-Monster Card. If a non-Monster Card is excavated, place it on the top of your Deck. You can only activate 1 "Berserker Soul" per turn.
