Shahrazad questions

[Abhorsen105]

I'm building a casual deck based on shahrazad (oxymoron?) and I just had a few questions

1. Can I death wish for permanents I own in the real game from the subgame?

2. If the answer to 1 is yes, then could I do the following:

play a spell
put it on the stack and play sharazad at instant speed (via spellweaver helix)
death wish for the spell on the stack from my subgame.

3. If I death wish for a card with imprint from the real game(spellweaver helix), does it stay imprinted with the same cards?

4. If my opponent concedes the subgame out of pure boredom, does that count as conceding the real game as well ?

Thanks,
Sam

1.  Yes.

2.  Yes.

3.  No.

4.  No.

Note that if you remove a card from the main game with a Wish, you don't put it back where you found it when the subgame is over.
