Okay how does fake trap works? If I use Harpie's Feather Duster on my opponent's field and he/she uses a Fake Trap? What happens?

Edo says the opponent hav to show the rest of the covered traps to show that he/she is not cheating right? How abt the covered magics? Do they hav to be destroyed?

Secondly about the recent rumours around my area that all magic cards hav to be covered 4 one turn before they could be used... So I was wondering if the rumours were true? Magic cards like Dark Hole, Raigeki will hav to be covered for a turn?

Thirdly could anyone explain to me about the speed thingy? I was scratching my head when I use Mystic Typhoon on my opponent's covered IO and he claim that he could still use Imperial Order first~ so I wondering whether Mystic should be faster or traps?
