"When this card is sent to the Graveyard while a "Laval" monster other than "Tender of the Laval Volcano" is in your Graveyard, you can send 1 "Laval" monster from your Deck to the Graveyard."
ok my question is about if this card is used as a synchro material, would i be able to get its effect when it is sent to the grave, and if i do when does the effect activate in the case for when i summon formula with it, do i mill first or would i draw first.
so basically in which order would everything happen, and would i, or would i not get the effect
