urgent tunning question

do the monsters have to be on the field or i can send them from deck to grave too?

* his card does not Synchro Summon the Synchro Monster from the Extra Deck. It allows you to perform a Synchro Summon. This Synchro Summon is performed the same way that Synchro Summons usually are done, including how you must send the Synchro Material Monsters to the Graveyard.

* To activate this card, you must control the proper Synchro Material Monsters to Synchro Summon a Synchro Monster.

obviously from field, since its how we synchro summon.
