If I use Jhoira of the Ghitu suspend ability on a creature card, does it retain the suspend ability after the card is casted? Assuming it does since Jhoria's ability does not state "until the end of turn?"
The suspend keyword gained by a card exiled with Jhoira won't be retained once that card leaves exile; in general, an object that moves from one zone to another becomes a new object in its new zone (C.R. 400.7).
