Are Yithian effects that trigger from the discard pile considered in play (on the table)? Or do they trigger and resolve from the discard pile?
"Cards cannot be moved out of attached discard pile for any reason."
My understanding is I can't trigger Interstellar Migration, as the cost of the effect is putting the card on the bottom of the deck.
But what about Lost Oracle? Her ability seems to be able to be triggered purely from the discard pile.
Yithian Scout would be similar. It looks like his ability can trigger, but Snow Graves would prevent him coming back onto the table.
Is my reasoning correct?
