Junk Mail

A Synchro Monster that used this card as material cannot be destroyed by battle. If this card is in your GY and you control a Synchro Monster with "Warrior", "Synchron", or "Stardust" in its original name, except during the turn this card was sent to the GY: You can Special Summon this card, but banish it when it leaves the field. You can only use this effect of "Junk Mail" once per turn.
