A plane card is treated as if its text box included “When you roll , put this card on the bottom of its owner’s planar deck face down, then move the top card of your planar deck off that planar deck and turn it face up.” This is called the “planeswalking ability.”

The controller of a face-up plane card is the player designated as the “planar controller.” Normally, the planar controller is whoever the active player is. However, if the current planar controller would leave the game, instead the next player in turn order that wouldn’t leave the game becomes the planar controller, then the old planar controller leaves the game. The new planar controller retains that designation until they leave the game or a different player becomes the active player, whichever comes first.

The first ability of The Aether Flues doesn’t target a creature. You don’t choose a creature to sacrifice until the ability resolves. Once you choose a creature to sacrifice, it’s too late for players to respond.
