Forum:Couple of questions

Ok so my first question is, when you have 2 poison chains on the field, and paralyzing chain, does paralyzing chain work twice? since the effects are separate?

and now I have a tough question

If my opponent has appropriate and destiny defender on the field, he has 4 pieces of exodia and all he needs is the last card in his deck, which is the only card.

Now when its my standbyphase he draws two cards, which is exodia, and then a deck out, but exodia doesnt activate in a chain, but then again is it a chain? Any ruling on that?
