Forum:Simulatneous card destruction

in the event that multiple cards are destroyed at the same time, e.g heavy storm, if i have gravity bind face up and activate imperial custom or imperial custom is already active , would all cards go or would gravity bind be protected by imperial custom, a similar question about geminis when energy bravery is on the field , if i played mirror force would there geminis survive and energy bravery be destroyed or would they all be destroyed. i always played on the assumption that the timing was thrown off and that cards would be protected but im not sure.
