Forum:Gem-Knight Lazuli Ruling

OK I was wondering about Gem-Knight Lazuli and Gem-Knight Obsidian effects. Can there effects miss the timing? Also will there effects work if they are discarded from the hand using Reactan, Elemental Dragon effect to summon Redox and/or Redox, Elemental Dragon 2nd effect to summon a monster from the grave. Thanks in advance. 50.27.47.23 (talk) 17:42, February 25, 2013 (UTC)
