Forum:Deck Out Questions

I have a few questions about Deck Outs. I just put together an Empty Jar deck, and I have to say I am very confused. Let me run down some things that I know real quick. Let me know if anything is incorrect.

If my opponent has 1 card in his deck, I cannot activate hand destruction. Based off of this, I cant force my opponent to draw cards if it isnt possible for them to do so. I assume its the same with gift of greed and others?

Morphing Jar, however, has a ruling that states that if My opponent cannot draw 5 cards they lose the duel. Why is this different from activating hand destruction? Is it because it is a mandatory flip effect and the other was a spell card? is the difference between mandatory and ignition?

Heres a few more questions. My opponent has no cards in his deck. I have a chainsaw insect. Can I attack? If I do attack does he lose via deck out? does this work because it is mandatory? or am I not allowed to attack?

If my opponent has 0 cards in his deck, and he has an iron core of the koaki meiru in his graveyard, does he lose automatically, or is he given the opportunity to take the iron core during his draw phase, instead of drawing, and preventing him from decking out?

These are basically my questions. Please help.
