Control changed cards with "if affected by opponents card" effects

This has been in my head for a while now so I’ll just ask.

If a card you own switches control, from anywhere from your control to their control (does not matter from where to where). Then returned to a place you control by your own card effect.

2 Situations
The card is on your opponents field (you own it) and you destroy or target it with a card effect.
Case 1: If this card is targeted by you opponents card effect you draw one card. Is targeted with enemy crontroller for a switch. Does someone draw? .And who draws
Case 2: f this card is destroyed by you opponents card effect and send to the grave, you draw one card.
Do you draw?

What it comes down to, where does a card check by who it was destroyed/ affected? On the field/affected location or in the grave.
If on the field does it recognize his real owner?
If in the grave, does it still counts your card as opponents card effect?

This is just another case of owner vs controller.

For your first situation, you destroyed your own card controlled by your oppononent, it is sent to the graveyard. No effect is given because you destroyed it and the effect would normally activate in the graveyard.

For the second situation, it's the same as the first. You only added sent to the graveyard.

Well, now it would form a Chain Link with your opponent drawing his card before you change control.

Chain Link 1: Enemy Controller
Chain Link 2: Whatever the card is

Resolve

Chain 2: Your opponent draws
Chain 1: You take control

Yes everything that Neon Cross said is correct. However be careful with Card Trooper since card Trooper must be sent from your side of the field to your grave so any if you destroyed your own Card Trooper on your opponent's side of the field you will not draw a card and neither will opponent.
