ok when this card leaves the field would it count for all lavals summoned after she is sent to the graveyard, or only the ones that are on the field at the time that she was sent to the graveyard? and if she was used for a synchro summon would the synchro monster also get the attack boost?
"When this card is sent from the field to the Graveyard, all face-up "Laval" monsters you control gain 200 ATK for each "Laval" monster in your Graveyard, until the End Phase."
