According to the Magic Tournament Rules, one of the accepted shortcuts is that when player A puts something on the stack, they automatically pass priority unless they specifically state they're holding priority. A corollary to that is if player A says they want to put multiple things on the stack (eg. "I activate Shivan Dragon's ability X times"), what they actually are proposing is to do it once, pass priority, and repeat X times.
An opponent, player B can interrupt the latter shortcut by saying "After the Yth activation, I do Z", in which case whatever player A planned on doing after the Yth activation is dropped, and they can respond how they wish. These shortcuts exist to stop play from turning into a painful slog of explicitly passing priority over and over, without those annoying "GOTCHA" moments where someone assumes you stacked a bunch of activations and try to blow you out (sidenote: these rules are relatively obscure so it's worth remembering them and not letting yourself get screwed).
This brings me to my main question, which has to do with Arcbound Ravager in modern affinity. The scenario often comes up where one wants to sacrifice all of their artifacts to Ravager, and it seems similar to the above shortcut, but unlike on Shivan Dragon, the order in which the artifacts are sacrificed matters. Of course if the opponent just says "Ok", then I sacrifice my board and carry on, but what if they don't?
If I'm in a tournament and I say "I sacrifice all of my artifacts to Arcbound Ravager", not knowing my opponent has a response, what will happen?
A) My opponent asks me to specify order, and I must give an order including ALL the artifacts I wanted to sacrifice. Then, if they decide they want to respond, they say which sacrifice they will respond to, and we carry on as normal. If they decide they don't want to respond, my board is sacrificed (I can't take it back!) and we carry on. This is the answer I gave my befuddled friend the other day, and the one that makes the most sense to me.
B) My opponent asks me to specify order, and now suspicious, I say I only want to sacrifice one artifact (say, Darksteel Citadel) to Ravager. My friend was arguing that this shortcut rule is bad because stuff like this can happen, but I believe that the rules don't allow for this kind of take-backsy silliness.
C) It's too late, my opponent calls a judge, and I get a warning for misrepresenting gamestate or miscommunicating?
D) Some other unlisted thing occurs?
