Tl;dr:
Can I use my Simulacrum to draw from a Deck of Many Things and if yes, what restrictions do apply?
Longer version
Imagine the following situation: You have gotten a Deck of Many Things and successfully identified it with an Arcana check, so you know what you got your hands on. Since you are aware how horrible the effects can be, you get a brilliant idea - at least you think so:
If I cast Simulacrum, let it draw from the deck and order it to give me whatever it got, I can draw from the deck without any risks!
It should be obvious that certain effects would not benefit neither you nor the simulacrum, e.g. the potential XP gains/losses, since you a) can't transfer XP and b) your Simulacrum can't gain XP.
I appreciate an RAI answer if there are areas that are not governed by strict RAW, but try to bend the rules only when necessary (or for a much greater fun factor).
