Creature - Djinn 5/6, 7U (8) Flying Morph {2}{U} When Maelstrom Djinn is turned face up, put two time counters on it and it gains vanishing. (At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.)1
Illus. Hideaki Takamura
If this turns face up then is somehow turned face down, it will keep the time counters and vanishing ability, which will continue as normal. If it is turned face up again, it will get more counters and a second instance of vanishing. Both would trigger each upkeep. [Future Sight FAQ 2007/05/01]
