Something is going on with the foil presales on this card. Foil presales are a terrible risk and most sites don't do them because it's nearly impossible to guarantee a given number will be opened. This card is part of combo decks that need cards in the graveyard, and this is silly in Nekusar, the Mindrazer decks. Still, we saw people move on foil Treasure Cruise early and the price never went down. Keep an eye on this.
