Forum:Flip face down

If i summon gandora dragon of destruction and i flip it face down by book of moon or tsukuyomi, will it still be destroyed by its own effect at the end of the turn? And also, if i use book of moon or tsukuyomi to flip mirage knight into face down after he invovle in battle, will he still be remove from play by its own effect?16:35, November 3, 2009 (UTC)
