Numberless Graves: ACTION: When an opponent's unit is destroyed, draw a card from the bottom of your deck.
If I use some card(for example:A Slave For Every Occasion) control my opponent's unit, then that unit be destroyed(just like be assinged enough indirect damage), could this situaction trigger Numberless Graves' Action?
I would say that till the end of the Slave Market effect the unit is under your control, so it is considered as yours.
So the opponent Units are those ones under his control at this time.
So in this case I would say that this effect is not triggered because the destroyed unit was under your control, so it was yours.

Kris is correct, and one of the recent FAQs clarified that when a card says "opponent's unit" or "your unit" it refers to cards that player controls, not cards he owns.
Thank you for answering.
I'm sorry I miss the clarified of recent FAQs, but I can't find that you say ""opponent's unit" or "your unit" it refers to cards that player controls, not cards he owns." in FAQ 1.4, would you please tell me where I can find that explanation?
(I totally agree this answer, I just need some document to convince my players)
I went through looking for it, and its not as descriptive as I thought it was. All it says is:
Players “own” cards that they included in the deck they are playing. Players “control” cards that they own, unless another player steals control of the card through a game effect. Any time a card leaves play, it reverts to its owner’s hand, deck, discard pile (as directed by the effect forcing the card out of play).
Here's a thread that has the official answer from James in it though.
