Is a creature (that transform) after the transformation the same creature? For example when the Thing in the Ice get targeted by the Merfolk Trickster and get transformed directly after, does Awoken Horror loss all abilities?
A double-faced card that transforms without leaving the battlefield, which is most of them, is still the same object it was before it transformed except with different characteristics.This means that when Thing in the Ice transforms in your example, Awoken Horror won't have any abilities and no creatures will be returned to their owners' hands.
