Forum:Stardust and Ordeal of the Traveler

What happens to Stardust Dragon if it falls under the effect of Ordeal of the Traveler? Is it returned to the Synchro deck, destroyed, or stuck into the player's hand?

If it is stuck into the player's hand, can it be summoned by using a synchro fusion, or is it just stuck to sit the rest of the duel out?
