When this card is Normal Summoned, if you have a "Laval" monster in your Graveyard other than "Laval Blaster": You can choose a number from 1 to 5, then send that many cards from the top of your Deck to the Graveyard; this card gains 200 ATK for each "Laval" monster sent to the Graveyard to activate this effect.
