Mighty Jinn

Question : Did the wording of this card change?

Answer : The first printing of Mighty Jinn said "When I leave the Expedition zone — You may put me in my owner's Mana zone (as an exhausted Mana Orb). If you don't, draw a card." Future pintings will say: "If I would leave the Expedition zone, you may put me in my owner's Mana zone instead (as an exhausted Mana Orb). If you don't, draw a card."

Question : What happens if Mighty Jinn is the target of a card that sends it to a player's hand or deck?

Answer : The controller of Mighty Jinn still has the option of sending it to their Mana zone.

Question : If my (Rare) Mighty Jinn is sent to the Mana Zone by another effect (such as Mana Reaping), can I choose to draw a card?

Answer : Yes! You may choose not to use Mighty Jinn's ability and therefore draw the card (it will still go to your Mana Zone because of Mana Reaping).
