Forum:Junk Warrior with Synchro Fusionist

In a TCG duel, if I were to Synchro Summon Junk Warrior with Junk Synchron and Synchro Fusionist as Synchro Material, whose effect would chain first, Synchro Fusionist's (an Optional Trigger effect whose trigger comes first), or Junk Warrior's (a Mandatory Trigger effect whose trigger comes second)?
