Question on the reborn effect of Night Train Blue Traveler
So this may be a Dueling Nexus bug, but I want to double check.
The effect in question says “If this card is in your GY: You can target 1 other EARTH Machine monster in your GY; Special Summon both it and this card, also you cannot Special Summon from the Extra Deck for the rest of this turn, except Machine monsters”.
The first turn I sent it to gy, I was able to revive it with no issues, but on future turns, I was unable to. I sent it to the gy by detaching it from an XYZ monster and I had other earth machines I could target to revive. Is there any ruling reason I would not be able to revive Blue Traveler on future turns? Does it lose the ability to revive if sent as xyz material?
