Sobald du die Kreatur kontrollierst, also übernommen hast, kannst du auch schauen was sich darunter verbirgt.504.3. You may look at a face-down spell you control on the stack or a face-down permanent you control at any time. You can't look at face-down cards in any other zone or face-down spells or permanents controlled by another player. The ability or rules that allow a permanent to be face down may also allow the permanent's controller to turn it face up. Spells normally can't be turned face up.
