I have test this deck once around the time when UB02 was released in Japan. I don't have a decklist anymore so there might be more cards aroud this combo.

Let me answer your question:

1. Yeah, you're not going to pull all of them in one turn.

2. I don't get it.

3. Returning a monster from its call cost (return Death Drain to your hand)

4. Depend on your deck.

This video might answer your question. Also maybe this one too.
