Sapazzan Skerry and Orvar
Hey! I know that you cast a spell and put it on the stack first before you pay any costs, which leads me to believe that if you were to cast an instant or sorcery targeting Sapazzan Skerry with orvar on the field, you'd be able to have the orvar trigger on the stack and copy the Skerry prior to tapping it, and thus copying it prior to having to sacrifice it. However, I'm not entirely certain that'll work, so I just want to check. Thanks!
