MTG Salvation

okay great Thank you so much for the replies. I gained some clarity on this.

I was doing some searching on here before I posted and couldnt find anything. Im very new to the world of MTG and I recently got Shapers' Sanctuary. I was playing a match against a friend and I already had that card on the field when he casted Kinjalli's Sunwing which causes creatures opponent controls to enter the battlefield tapped. My argument is that for every creature I cast thereafter I should be able to draw a card due to Shapers Sanctuary which whenever a creature you control becomes the target of a spell or ability an opponent controls, you may draw a card. My friend feels that the ability of kinjallis sunwing is affecting how i how i cast my creatures and not them specifically and as such I should not be allowed to draw any additional cards. Any help with rulings on this would be great. Thanks.
